I’m facing an error while trying to run my orchestrator in IIS. As it is showing the below error
"Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
What this message means is that application waited for a database connection but the timeout expired before it could get a connection, probably because the number of connection in the pool was too low for the number of connections that were attempting, or there was a network time out, i.e. the connection between your IIS and your SQL Server was too slow to serve a connection.
Check below thread:
Thank you @Akash_N_Jain. I will check and get back to you.Actually, it was working yesterday,but all of a sudden it started showing the above mentioned timeout error.still not able to fix even though I tried to increase max pool size in my connection string
