MINERVANET - Error Report #39 - Failed to fetch

@sascha.herzinger

Sometimes we have network issues. Details can be found below.

There are few things that we might consider here:

  • provide an url to the file that Failed to fetch, right now it's plain: stacktrace: Error: Failed to fetch
  • in case of the error reporting, for this specific issue (and maybe Error: The network connection was lost. #807 (closed)) I would think about providing popup with information: 'We had problems with fetching some information from the server. Please retry. If the problem persist please report the error to developers.' And report the error should be a button opening report error info windor
  • maybe we can identify the problem by itself? it happened to me from time to time, but I couldn't see any pattern, any ideas? F5 magic firewall rule?
