HI,

Below is the error message I am getting while trying to do seeding, my openstreetmap.

mapproxy.source.wms - WARNING - could not retrieve WMS map: Error during CGI call (exit code: -9)

That’s just a stacktrace. What are you actually trying to do?

Please try and explain without assuming that people know what “MapProxy” is or what it is normally used for - people might not be familiar with the software, but might have an idea what the problem is, and if you explain what you are actually trying to do they might be able to help.

Apologies if it’s not relevant, or you’ve read it and are following it to the letter, but it might also be worth reading https://operations.osmfoundation.org/policies/tiles/ .
