[fernandog]

Need to fix #856

Requests.exceptions.ConnectionError is not being catched. any idea?
looks like an error inside another error

@medariox @ratoaq2

[ratoaq2]

I didn't get it. The old code is actually catching ConnectionError

[fernandog]

@ratoaq2 yes. But labs rewrote another part.

Line 1337 as in the error
