gitea:3000 isn't resolvable from act_runner's job containers, which run on their own Docker network. With the panorama downscaled in common the jars are ~45 MB, under the Cloudflare tunnel's 100 MB request limit, so upload through github.server_url again. Fail with a readable error before uploading if any jar is 100 MB or more. Co-Authored-By: Claude Opus 5.5 <[email protected]>
