Problem
You receive a proxy error if you try to open the dashboard
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request
Reason: Error reading from remote server
Solution
If you receive this error check the routing table on the host, where the dasboard backend is installed
route
You should find the route to the dashboard network in the bottom of the output. It should point to the dockerX interface. If there is a route to another interface above with the same target network, this should be the problem. Find the corresponding UCR variable by executing:
ucr search --brief interfaces/<interface>/route/ |grep <docker-target-net>
You need to replace and with your values. You can delete this route by executing
ucr unset /interfaces/<interface>/route/<netzrouteX>
