One of my customers is experiencing the following problem with 4D Server v17R3 running on Windows Server 2016 64-bit.
In their code they use in various places Begin SQL / End SQL to access the 4D database through SQL. This has worked fine for years.
Since last Friday, they now get an error message each time Begin SQL / End SQL is used. The error message is: “Error 1002: Failed to connect to the remote server. Error 60: Operation timed out.”
The same code works fine when I test on a different computer.
I have checked for the obvious things:
- Restart windows
- Check if 4D’s SQL server is running (although I think this is not required for Begin SQL).
- The ports 19812, 19813 and 19814 are open and not blocked by a firewall. I can successfully connect to port 19812 using 4D Internet Commands.
But still the same problem.
Does anyone have any good tips?
