One of the challenges especially with SQL Express is that you need to enable some protocols on the network level first in order to connect to it. You might see an error message the one below when you try to connect to SQL – stating SQLState 08001 and Error 17.
In order to resolve this, you need to enable named pipes and TCP in the SQL Server Configuration Manager that was installed by default on your system. See the image below on how it should look like. Please note that you need to restart the SQL service in order for those changes to take effect.
Please note – there might be a need of additional configuration like the Windows Firewall or other parameters, the above just addresses a rather common issue.

I had a similar problem and the solution was to restart IIS.
For this, just go to Start and open Command Prompt as administrator. Then type iisreset and hit enter. After a few seconds, everything may be up and running again.
Hope it works for you and for others with similar issue.

Disclaimer; This is not «the solution», just the same behaviour and how to bypass it. Very little info on the matter and I have tried for a month to find what causes this.
We have the exact same behaviour on Windows Server 2019 (also 2016), IIS w PHP 7.3 and Azure SQL. (drivers 5.3 to 5.7.1 tested, PHP 7.1 to 7.3 tested)
This seem to be a connection issue, came with windows update and the code is valid but will not be able to connect from time to time. When it first crashes no connections will be made until IIS reloads fastcgi.
What server OS is this on? (On Linux we do not seem to have this problem)
Have no idea but seem to be the driver and OS related, if we specify ODBC in the connection string it does not seem to crash but it does not handle all charsets out of the box with ODBC driver. You can fix that programatically though.

we downgraded to Windows Server 2012 R2 and now it seems like the issues are gone (we run Azure and AWS instances). Azure SQL seem to be closest related to sql server 2014.
For the Windows 2012 servers I did install the PHP 7.3.7 package that came with «web platform installer» and also the SQl Server driver 5.6 for that PHP version.
Don’t think it is neccessary or needed for the SQL connections but have added curl and ssl cacert path in php.ini (it is needed for pushing data to AWS S3 though).
I also tested IIScrypto to adjust registry settings to use either TLS 1.2, all TLS, different cyphers, the solutions in the above links but no success.
The problems started with windows update or possibly a sql server update and it is intermittent making it hard to find out. Clearly related to communication but not reproducable «on demand».
We are moving the solution to a Linux platform as soon as the rest of the legacy (.asp/.aspx) scripts are converted to php.
My best bet is to use the latest php and latest sql driver from «web platform installer», also update to latest ODBC driver if you need but we are running now with the version 17 (2017.173.01.01) 2/14/2019 that came with the Windows server 2012R2 image.

Errors like SQL server connection failed SQLState 08001 can be really annoying.
The SQL server connection failed 08001 occurs when creating an ODBC connection on the Microsoft SQL.
At Bobcares, we often get requests from our customers regarding the SQL sever connection error as part of our Server Management Services.
Today, we’ll see the reasons for this SQL sever connection instance and how our Support Engineers fix it.
When the SQL Server Connection failed: SQLState 08001 Occurs?
Mostly the error SQLStateServer Connection failed 08001 occurs when creating an ODBC connection on Microsoft SQL.
We click Next on the SQL login screen. Then using the login information provided, the ODBC manager will try to connect to the SQL Server. But after some waiting time, it displays the below error message.
The main three reasons for the error SQL Server Connection failure are
- If we provide a wrong server name.
- If the SQL Server not configured to a network connection.
- The other possibility of this instance if we provide an incorrect login name or password.
How to fix SQLState 08001 Error?
Recently, one of our customers approached us with an error message ‘SQL Server Connection failed: SQLState 08001′.
Our Support Engineers log in to SQL Server Management Studio and make sure that the database name and other details are correct. In case, if the database server name is wrong then this error can occur.
Sometimes the message appears when we use ‘localhost’ as the Database Server name on the Database Settings screen in Confirm. But we can log in to the database in SQL Server Management Studio as a user, using the Server name ‘localhost’. Then our Support Engineers make any of the below two changes to fix the error.
- In the Database Settings screen, we change the Database Server name to the server name or
- In the SQL Server Configuration Manager, we enable the Named Pipes values in the Client Protocols.
Our Support Engineers follow any of the above two methods to fixes the error while creating an ODBC connection on Microsoft SQL.
[Need assistance in fixing the Error while creating an ODBC connection? – We can help you.]
Conclusion
In short, we’ve discussed that the SQL server connection failed SQLState 08001 occurs when creating an ODBC connection on the Microsoft SQL. Also, we saw how our Support Engineers fix the error for the customers.

SQL Server Error:11
[Microsoft][ODBC SQL Server Driver][Multi-Protocol]General
network error. Check your network documentation.When I test ODBC connection it completes successfully and I also checked permission and seems to be okey and also checked security in
SQL database it has permission to connect to corresponding database. To let you know guys I recently changed the password of that machine to blank and urged my colleague to change in next login so is it because of password
its not connecting. I am using TCP/IP dynamic port in ODBC connection. One thing I dont understand is that why its functioning well in all clients except one which I checked previous day before changing password it was working fine.I am
using sql server 2000 and access 2003 database.GUYS HELP HELP!!!!!
Cheers

What is your client operating system? If it is Windows XP or earlier version, please first check the client settings:
1. Check your SQL Server Client Network Utility settings.
Open SQL Server Client Network Utility by running Cliconfg.exe from command prompt on your client machine, selected the General tab and make sure that the TCP/IP protocol and named pipes protocols that your
SQL Server support are enabled. You can check what the protocols your SQL Server support by running SQL Server Server Network Utility at your server side. Make sure that they are equal and then you can create an alias with the sql server name with a
specific protocol like TCP and TCP port in the Client Network Utility. The alias must be the name that you used to connect to your SQL Server instance.2. If the above does not work, please check if there is any problem of your MDAC with MDAC checker,

3. Make sure that your client operating system has the latest service pack installed.

When creating a connection to SQL Server using an ODBC driver, you might receive this error:
Connection failed: SQLState: '08001'
Here are some common causes and corresponding fixes:
1. SQL Server service is not running on SQL Server.
You can try to start or restart SQL Server services, including SQL Server Database Engine, the SQL Server Agent, or the SQL Server Browser service.
2. SQL Server Browser service is not running on SQL Server.
This might cause the issue sometime so make sure to enable the “SQL Server Browser” Service and set to start Automatically.
3. TCP/IP protocol is not enabled for SQL Server.
Make sure the TCP/IP protocol is enabled by logging in to the SQL server, navigate to the “Sql Server Configuration Manager”, then enable the “TCP/IP” and the “Named Pipes” Protocols.
4. Firewall on SQL Server is blocking TCP port of SQL Server.
Check and reconfig the firewall rules to allow SQL Server access.
5. Firewall on SQL Server is blocking UDP port (1434) of SQL Server browser.
Again, check and reconfig the firewall rules to allow SQL Server access.
