Opening JDBC connection to Some(<my mendix server>) failed with SQLState: 08S01
0
Hello, We are running Mendix on a on’premise architecture an we regularly get this kind of error: “Database connections: 0 active, 5 idle.” “Opening JDBC connection to Some(<my mendix server>) failed with SQLState: 08S01 Error code: 0 Message: The TCP/IP connection to the host <my mendix server>, port 1433 has failed. Error: "<my mendix server>. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.". Retrying...(1/4)” And when we have these message, the application is no more reachable; we have to restart it to make it work again... We checked our database and there is no issue with it: it is reachable and it run fine. Do you have an idea of what can cause these error message for information, our database is a SQL Server 12.0.2000.8 Thanks in advance

No idea??? I tried to restart the server where the application is hosted but it didn’t solve the issue…
I cannot restart the server where the DB is located because it is an Azure DB… Just for info, our Mendix server is also an azure server. So it should be no issue with the connection between these servers and it worked fine for at least 1 year…
