I was trying to restart the Home Assistant front end and if I use the restart option under the system menu or in the developer tools section absolutely nothing happens and Home Assistant doesn’t restart. I have tried clearing my browser cache tried with Chrome, Edge and the IOS Home Assistant App and I cannot restart the only way I can perform a restart of the front end is by physically shutting down and rebooting the host PC.
In the developer tools yaml section perform a config check. Even if it passes take note of your persistent notifications and logs. Errors may be reported there.
I actually did a config check last night and it never completed, I was tired so I went to bed.
It made me wonder if somehow the configuration.yaml was corrupt so I made a backup then deleted it and physically rebooted the PC. Once back in I went through the file and removed a couple of lines I didn’t need any longer and added everything back and now the perform check works correctly and I can restart Home Assistant from either developer tools or system menu
I guess something must have gone sideways with the original configuration.yaml
