This does not look like an application issue.
this looks like a network or environmental issue.
I can find only two cases reporting this error and both seem to be have been environmental.
We would need a lot more detailed information to help further than just the little error in the title.

This seems to still be a problem in 20.1 after trying the above suggestions. Has there been any update on this issue?
