Blank start page, browser got 502 load errror

[tommi2day]

This morning i only got a blank TOS starting page. digging into the browser developer console i found tries to load tos lang data resulting into 502 status. Also in private browser mode. Calling the url directly i got "Bad Gateway" response from nginx. All other services operated as usual, only the TOS Gui was affected. Response from nginx. In nginx error log i saw such entries:

2023/06/15 12:09:28 [error] 2986#2986: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.xxx.xxx, server: znasnginx, request: "GET /v2/lang/tos HTTP/1.1", upstream: "http://127.0.0.1:5050/lang/tos?", ...."

Only a reboot solved the situation.

What could be the reason for such bad condition preventing all administrative tasks?

This problem may be caused by hard drive errors, viruses, or running blockages
We suggest that you try reinstalling TOS, which can generally solve other issues besides possible hard drive errors.
