We recently upgraded our Enterprise environment to 11.1. Since then, we've had performance issues of varying degrees. The most common issue is when a map/app is left open in the browser for 10 minutes or so, the map services will stop responding. Occasionally, it will log users out and ask them to sign back in. Generally, when you reload the page, everything will load. This seems to happen regardless if it's in the Map Viewer, Web App Builder, or Experience Builder. However, I do not have this issue in Dashboards or any of the mobile apps. I've configured the pooling settings for several map services that I thought were causing the issue, but that doesn't seem to have helped.
I'm also receiving an error in our Server Logs that says the Portal server may be unreachable. I've attached screenshots of the errors.
I've started a case with Esri support but haven't had much luck yet. Their suggestion is to reinstall Web Adaptor and see if that does anything. Part of me wonders if doing a full reinstallation would be worth it.
If you have any suggestions, I'm all ears.
