I've installed pgAdmin4 v2 on Windows 7. The installation went fine and I could launch it successfully without any issue. After couple of days, now if I try to load GUI I am getting the error – “pgAdmin 4 Desktop Runtime has stopped working”. Log file shows below error entries:
raise URLError(err)
URLError: <urlopen error Tunnel connection failed: 407 authenticationrequired>
2018-03-26 13:16:01,937: ERROR pgadmin: Exception when checking for update
Does anyone know how to fix the issue?
Version check was root cause of the problem as my network has restricted access. Disabling version check in application config settings (UPGRADE_CHECK_ENABLED = False in config_local.py) fixed the issue in my case.
