Hi Friends,
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."
Thank you
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
