I am not a employe but I cant confirm this as I cant reproduce it.

Thanks for filing the issue!

This issue seems to be similar to Issue:  893958 , hence merging into it and marking it as Duplicate.
Note: Feel free to Un-Dupe it if not the case,

@Reporter: Could you please let us know which Antivirus is installed on the system(...if any).

(Unmerging so we can track this better.)

This is likely due to a buggy antivirus, firewall, or proxy on your machine or network. Are you running Kasperksy anti-virus? If so, does it work if you disable it, specifically the "Scan encrypted connections" setting? It seems they recently shipped a bad update and broke stuff.

Otherwise, what anti-virus, firewall, proxy, etc., do you run? It would also help us to get a NetLog of what occurred if you can reproduce it, see details here:

Thanks!
