Blueprint is Non-Responsive After Suspending for the Night

[tsmaeder]

Bug Description:

When I tried to "Open Folder" this morning after leaving Blueprint running overnight, nothing happened. In the log, I found 3 instances of this message:

Failed to load resource: net::ERR_NETWORK_IO_SUSPENDED localhost:53433/socket.io/?EIO=4&transport=polling&t=ObE4dje&sid=eMQ_VeA3TV2iGx0GAAAK:1 

It seems anything requiring a connection to the back end (like opening a file from the navigator) is non-functional. Refreshing the window fixes the problem.

Additional Information

• Operating System: Windows 11
• Theia Version: Blueprint 1.39.0

@msujew since you are savvy about socket.io, maybe you can comment what the problem might be?

@tsmaeder I also cannot reproduce this anymore, I suggest to close it. Great fix!
