After upgrading firewall to R80.20, Capsule Workspace for IOS had a problems connecting with the GW.
Problematic devices were working properly with R80.10 before upgrade, and I have successfully tested them recently against other R80.10 GW.
All Android Capsule Workspace clients are working properly, also web portal of Mobile access is working properly.
There are nothing usefull in logs.
Does anyone has faced such problem?
