Update on that topic if someone have the same issue => Install a fresh Secure gateway solve the issue. After a call to the support and 2 debug sessions, Dell support was 100% sure it was a network issue on our side. After the fresh install using same IP, config, ... it's working so for me it's more an issue with docker during the migration from ESRS to secure gateway.
Hi, After 2 days of test and research, I ask the help of the community for my issue. I have correctly upgraded ESRS to Secure connect gateway. After the upgrade I can connect to the web page to finalize the setup, but I can't go to the Authentication step due to error. I'm not using a Proxy server, so I let everything blank but I got this error message. [IMAGE] I have looked with my Network team, the 443 and 8443 ports are open and the traffic looks good.
