Hi there, my Orchestrator was running smoothly until a patch was installed in my server and cause it to go offline.

I need help on two things,

Question#1: All my licenses are in orchestrator so i can not do anything with UiPath Studio since it depends on orchestrator connectivity. So how do I activate my UiPath Studio once instead of it depending on orchestrator.

Question#2: Orchestrator is down because of Timeout expired due to max pool size

Below is a detailed Error Message (Stack Trace) please assist me.

[InvalidOperationException: 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.]
