Problems in accessing files in GS

Hello, lately I have had problems in accessing files in GS: according to my system the problem is with the remote server, but my agency checked and everything is working normally on their side. After a few tries (I need to reconnect the server in the settings) I can access, and then I get the same problem in checking out the file. After a few tries I can check out the file, and then I have no further problems. The IT dept in my agency was not able to fix this. Any ideas? When this problem started I was working with Studio 2019, then I installed Studio 2021 with no improvement. I hope somene can help me with this. Thank you
