Hi Railway Team, I am reaching out regarding my apex domain [**aureacommkt.com.br**](http://aureacommkt.com.br/) (Project: **adorable-victory** / Service: **aurea\_commkt\_site**). The domain has been stuck in the "**Issuing TLS certificate**" state since April 13th (\~16:30 UTC-3), exceeding the 72h window. **Technical Diagnostics:** 1. **DNS A Record:** Pointing to `151.101.2.15` (Confirmed via `dig`). 2. **Verification:**`_railway-verify` TXT record is configured and verified (green checkmark). 3. **HTTP/HTTPS Status:** HTTP returns 301, but HTTPS fails with `SSL: no alternative certificate subject name matches target host name`. 4. **Apex Limitation:** My registrar ([Registro.br](http://registro.br/)) does not support CNAME on apex, so I am using the required A record. 5. **Subdomain Status:**`www.aureacommkt.com.br` is working perfectly via CNAME. 6. **No Blockers:** No CAA records are blocking Let's Encrypt, and DNSSEC is active/valid. **Potential Conflict:** I see a warning: _"You have hit the custom domain limit for your plan"_. Could this internal limit be blocking the automated certificate issuance for the apex domain? **Attempted Fixes:** * Clicked the re-verify () button multiple times. * Redeployed the service. Since the DNS is correctly propagated and verified, could you please manually trigger the TLS issuance for [**aureacommkt.com.br**](http://aureacommkt.com.br/)? I intend to stay on my current plan and do not wish to change DNS providers. Sincerely, Regina Gravina

Apex Domain (aureacommkt.com.br) Stuck on "Issuing TLS certificate" - Over 74h

Hi Railway Team,

I am reaching out regarding my apex domain aureacommkt.com.br (Project: adorable-victory / Service: aurea_commkt_site).

The domain has been stuck in the "Issuing TLS certificate" state since April 13th (~16:30 UTC-3), exceeding the 72h window.

Technical Diagnostics:

DNS A Record: Pointing to 151.101.2.15 (Confirmed via dig).
Verification:_railway-verify TXT record is configured and verified (green checkmark).
HTTP/HTTPS Status: HTTP returns 301, but HTTPS fails with SSL: no alternative certificate subject name matches target host name.
Apex Limitation: My registrar (Registro.br) does not support CNAME on apex, so I am using the required A record.
Subdomain Status:www.aureacommkt.com.br is working perfectly via CNAME.
No Blockers: No CAA records are blocking Let's Encrypt, and DNSSEC is active/valid.

Potential Conflict: I see a warning: "You have hit the custom domain limit for your plan". Could this internal limit be blocking the automated certificate issuance for the apex domain?

Attempted Fixes:

Clicked the re-verify () button multiple times.
Redeployed the service.

Since the DNS is correctly propagated and verified, could you please manually trigger the TLS issuance for aureacommkt.com.br?

I intend to stay on my current plan and do not wish to change DNS providers.

Sincerely, Regina Gravina

Your apex domain's DNS currently has a static A record pointing to 151.101.2.15, but we expect a CNAME (or CNAME-flattened equivalent) pointing to 38eszgol.up.railway.app for certificate issuance to work. Since Registro.br does not support CNAME flattening or ALIAS records on the apex, a static A record will not allow us to issue a TLS certificate. Our docs on adding a root domain describe a workaround: you can change your domain's nameservers to Cloudflare (which supports CNAME flattening), then add a CNAME record for the apex pointing to the Railway-provided value.

"I understand the CNAME limitation at Registro.br. However, many PAAS providers allow TLS issuance for Apex A Records via HTTP-01 challenge. Is it possible to trigger a manual HTTP-01 validation for my A Record (151.101.2.15) instead of relying on the CNAME check?"

We don't support manual HTTP-01 validation or any alternative certificate issuance path for apex domains. A CNAME (or CNAME-flattened equivalent) pointing to your Railway-provided value is required for both routing and certificate issuance.
