I have a couple of SG250X -24 port wit firmware 18.104.22.168, after a while the web interface is not more reachable through https protocol, I need to enable the http server via cli.
I upgraded the firmware from 22.214.171.124 version to try to resolve this problem, did any else resolve the same problem?
Solved! Go to Solution.
A lot of "Failed to load resource: net::ERR_EMPTY_REPONSE" and "Uncaught TypeError: Cannot read properties of undefined (reading 'setTokenWithError')" ... nice
Can you post screenshot to look, also I would suggest to open a SMB tac case to investigate for you.
If you still looking to resolve by your own.
take the config backup from the device.
reset the device to factory
upgrade to latest firmware (in case required, )
restore the config and testit.
thank you Martin, it's necessary to enable the secure web server from CLI and not from web interface, followed your suggestion the problem was resolved.
