I start a new server, and only install fabric api 0.36.1,it's show the error message (DecoderException: java. util.zip.DataFormatException: incorrect header check)

Please try reinstalling fabric api, this looks like a corrupt jar. Then if it still doesn't work please send the full log.

latest.log
(update to 0.37.0 )

Can confirm, had the same issue when updating my server from 1.17 to 1.17.1, I made sure everything was up to date about three times (that was on Sunday). Had to switch to Vanilla for now. Interestingly it didn't happen on my local test server, even though I have the same Fabric version and mods there.

Same, my local connection (in same device) everything correct.

I had this issue as well. I fixed it by removing the .fabric directory in your main minecraft directory

Thank you so much, that seems to have fixed it for me :D

Mind explaining what steps you used to update your server so it can be reproduced by us? This is likely an issue with the way the upgrade happened (possibly a fabric issue).
