The wildcard cert + HTTP 301 with the Railway header both confirm traffic is reaching Railway's edge fine, so routing/CNAME isn't the problem — this is isolated to verification/cert issuance. Two things to check:

1. The ownership TXT, not just the CNAME. A VALID CNAME doesn't mean verification passed. "Waiting for DNS update" also covers the _railway-verify ownership record, which Railway checks separately. For portal.workcompworld.com that record lives at host _railway-verify.portal, value exactly as shown in the domain's "Configure DNS Records" modal. Confirm it resolves:

dig TXT _railway-verify.portal.workcompworld.com

If it's missing or on the wrong host, that's the stuck verification — issuance never starts regardless of anything else.

2. Stop deleting/re-adding the domain. Each re-add on an unverified domain produces a failed Let's Encrypt authorization. LE allows only 5 failed auths per hostname per hour (refills 1 every 12 min), plus a 5-per-week duplicate-cert cap — several cycles in a day trips both. If you're rate-limited, no cert issues until the window refills, and re-adding only burns more budget. Leave it in place.

Fix the TXT, then don't touch it. Railway's provisioner retries on its own; once verification passes and a rate-limit slot frees (full recovery ~1 hr), the cert auto-issues. If it's still serving the wildcard cert ~1–2 hrs after the TXT is confirmed correct and you've stopped re-adding, open a thread with Railway and mention the repeated re-adds explicitly — they're the only ones who can read the actual ACME error and confirm whether you're in a Let's Encrypt rate-limit cooldown on their account.
