Unable to submit updated package to Flathub: Repository update failied

I am facing the exact same issue with my app (fr.arnaudmichel.launcherstudio). The build succeeds, but the post-publish step fails with a connection error to the internal server. Job ID: 488230 Error: curl: (7) Failed to connect to front-sov.wombat-salmon.ts.net port 80 It seems like an internal infrastructure/networking issue.
