When accessing through CNAME, it works fine, but when accessing through a custom domain, I receive the message “Run this Repl to see the results here.”

My website is http://vngcooper.com/ The current time is 11:35 05/04/2023 (GMT+7:00) and it is still experiencing the error.

This error occurs suddenly and usually resolves itself within an hour. This is affecting the SEO of my website.

I have never connected a custom domain to my Repl so idk how to solve this. :frowning:


although the error is not fixed but Thank you for trying to help me

Can we have a link to the repl that is connected to that site please?

Yes, 72b9db0b-4679-4b1a-ac2f-a964dc277fb4.id.repl.co
here is its CNAME. currently on this link, it’s still working properly

You have both a CNAME and TXT record on the main site correct?
Also please provide a link to where your repl is on replit. (Should look like https://replit.com/@Username/Replname)

i used ip address instead of cname. i have filled in the entire txt record and ip address correctly

however I use hacker replit and am not willing to share its source code

The IP address of repls changes quite often, and as such a CNAME link to the repl’s IP will not work, as at the very least it will not work consistently. I recommend you relink your custom domain and follow the instructions to the T so that way you can ensure it links properly.

I find using CNAME less error prone than using ip address:

I’m not sure I understand what you mean. Please try un-linking and re-linking your custom domain to your repl and see if that fixes it.

i tried and it didn’t fix

it’s been buggy for almost 2 hours. this makes me very worried

Did you remove the CNAME and TXT records from your site before trying the un-link and re-link? if not, try that.

I use ip address instead of CNAME

This should not be done as repl IP address change frequently, and as such cannot be guaranteed to work.

Thanks for the reminder. so I use CNAME instead of ip address right

Re-checking the Domain linking thing (Which I have not done in a while), It does appear there is an option for IP (A record) linking. However the IP should not be in a CNAME record (Which I thought you said earlier).
