Need help on rate limit for connection to Domino server

Hi,

Is there any rate limit to connect to domino server accounts?

The scenario is through our project, we are trying to run concurrent flows where we are trying to perform the various actions on domino accounts and after sometime, we are getting 401 i.e.Timed out while authenticating with server.

We are not able to find out the reason whether this is a problem with domino accounts or the library which we are using to connect to domino server.

Awaiting for reply.

Thanks
