Hi @arundevopschat ,
Just such an error message may not be able to determine your current problem. There are many reasons for this error. Have you configured the timeout duration for these services? And I found that IOMSONLINEWithKey.Service1.GetComplaintDetailsCA(String key, String CANo), are you accessing the database? If this is the case, there may be a problem with the database connection, such as the connection string?
If possible, could you provide more details? It will help us to help you find a solution to your problem.

We have increased timeout.
Database is working fine as same database is used by 3 more application and is working fine.
Will changing string to stringbuilder will help

This api is using POST method
Connecting to database based on contract no fetching details

Hi @arundevopschat ,
Is there a lot of data processing in the code? For example, multiple calculations of string objects result in multiple allocations of memory.
Do you clean up resources in a timely manner (release the connection back to the pool)?
The above are just my guesses. If possible, please provide more details.
