About a month ago we upgraded to 2020.6 and some of our users are reporting regular errors in the browser
"There was a problem with your request.
Unable to establish a connection to the Octopus Deploy server. The server may be offline. Please check your network connection."
Looking in devtools we see a number of api requests failing with net::ERR_CONNECTION_REFUSED.
I get this sort of error very occasionally, but other users say they get it very often, one user told me he would estimate he gets the error 80% of all page loads. The page will partial load but most will be blank
