Hey @albertnerikat,
sadly most of the time the timeout is not the problem (unless you really want to wait for 15 minutes to learn that you didn’t receive the response).
Similarly, how recent this started have little to do with the problem as this could be the problem with the “other side” or connectivity somewhere in between the host running the workflow and the destination server (a.k.a “in the Internets” 
).
If there is a support channel for mcp-atlassian, you could ask there as well, maybe they have a way to retrieve logs or know about any ongoing issues with reachability.
