There's an issue with our site where many users who log onto our site get a connection refused/connection timed out error. It depends on the wifi they are using. The issue is a conflicting c name and a record on railway.

Would you mind sharing a screenshot of your DNS configuration?

On some networks it doesn't connect properly. It's only for this domain (aibverify.com), we tried it on other domains and it works fine. Conversations with godaddy and Coudflare support told us that the issue is conficting c name and a name records on railway.

below are the errors, let me know if I can clarify anything:

Hello, just wanted to follow up for anyone that can help, thank you.


8 months ago

there's not much we can help with here as this is not a platform issue but an issue with networking on your side, as previously mentioned, the domain works for me without issue

@Fragly - does it work for you?


8 months ago

yes, works fine for me

Would you be able to help change the a name? I've contacted ISPs, Cloudflare, Go daddy. They've all said its a conflicting c name and a record, and I need to switch the a name


8 months ago

you should not be using an A type to begin with, you need to only be using a CNAME, the cname you where given when you added the domain to railway

This is what I thought as well, but I was told otherwise. It doesn't let me add the a name to cloudflare to begin with, but they said it's because it is misconfigured. Have you ever worked with someone who has had a similar error, where they are unable to access a website through certain Wifis (ISPs) and have been through other?

Thank you for your help. Railway support has been the most repsonsive as opposed to other parties I've been corresponding with.

all looks good to me, there are no issues there, and there are no A types at the root


8 months ago

if the domain doesnt work, than its something to do with the ISP, and theres nothing railway, cloudflare, hostinger, etc can do about that


pranavmr100

So we tested that out as well - we changed the domain name to "dealerhedge.com" - all other settings were kept the exact same, and it worked

All the people that were running into the issue likely because of the ISP before, were able to access the same site via dealerhedge.com, but when we switched back to aibverify.com - it stopped working

This is why it's a very confusing error for us

I understand thank you anyway. Do you know of anybody else we can contact to fix this issue? We've contacted cloudflare, go daddy, and you guys at Railway


8 months ago

your ISP, since this is not an issue with any of the platforms you just mentioned


pranavmr100

But it sadly doesn't work on various ISP's not a singular one

Contact all of them?

NYC, my team is located in Austin, and LA. It works when we switch to mobile data, but doesn't when we use Spectrum/verizon

are you using the default isp dns?


pranavmr100

Yep


8 months ago

try not doing that


pranavmr100

We can switch our Dns's but will that solve our issue? If we switch our dns's and it works for the three of us, it won't solve the issue for other users who try to log into our website but have the default ISP dns's (exhibit A: my parents, who are in California, have tried to log in and it doesn't work for them, and they don't know what a DNS even is - they will also tell me it's "too complex" if i try to explain it to them)

its a test, while it doesnt fix the issue, it helps you understand the problem

We've checked, and even changed SSL certificate on cloudflare with no luck



hey, could you maybe try disabling Cloudflare's protection? maybe that will narrow down the cause


pranavmr100

Totally, we did try that initially, but it's been a while and can try it again


yep, try that, wait a while for the dns cache to go away

and then do a curl

I would enable always use https, but other than that, this isn't a problem with the railway platform
