Steps to replicate the issue (include links if applicable):
- go to https://commons.wikimedia.org/wiki/File:MNHN_1892.png and click the blue button to see the georeferenced map on Wikimaps Warper
- the link leads to the page https://warper.wmflabs.org/wikimaps/new?pageid=114574493 where there is the following error: "502 Bad Gateway nginx/1.18.0"
- https://warper.wmflabs.org/ has the same error
- something seems strange on the following graphs of Grafana, between October 24th and 26th: https://grafana.wmcloud.org/d/0g9N-7pVz/cloud-vps-project-board?orgId=1&var-project=maps&from=now-7d&to=now => the graph of "maps-warper4 network usage" goes down to 0 and the graph of "maps-warper4 RAM" suddenly increases and stays constant at a high level.
What happens?:
I get the error "502 Bad Gateway nginx/1.18.0" on any page of Wikimaps warper I try to visit
What should have happened instead?:
I should see the (great!) web interface of Wikimaps warper
