Some user requests not reaching railway backend
Our main app is deployed on railway and for some users the requests don't even reach backend. Users have tried multiple accounts, devices and even internet connections. Is railway blocking some IPs? If yes how to unblock them?

N/Acan you go into more details please? "not reaching railway backend" is not too helpful
Its very weird for us also. For some IPs it seems like the backend isn't responding or is inaccessible
None of the backend requests seem to be reaching backend
may i know your geographical location?
The server is singapore
Im asking for your location, not the server
India
are you able to reach the backend?
7073773c-bae3-4648-b179-72dda4777e8b is the project ID
Yes
where are the users located that cant access the backend?
Northern India
they are likely behind some kind of local firewall
How can that be bypassed?
they would need to use a VPN
issues suddenly come up. for a long time they were able to login, suddenly they are unable to access
theres nothing railway can do about users who are behind a firewall
can you guess why they would face this after being able to sign in once?
im sorry but i would not have an answer for why whoever is controlling the firewall they are behind has added railway to the block list
Thanks for your help!!
im sorry you are facing this but it would be out of the control of railway
yes very frustrating for users and us π
Anyway we can verify this?
redeploying would change IP and if user is able to sign in maybe that should confirm?

Local firewall could be likely, but it's very weird that they were able to access the server and now they're not. I'll second Brody's suggestion to try a VPN, but come back if they're still unable to access it
Okay. Any way to verify this issue?
Test with a VPN and report back

This request is not resolving plus some others
please be more specific when you say not resolving as that could mean many different things
getting error ERR_NAME_NOT_RESOLVED
on user's webui console
that seems like railway domains have been blocked by your DNS resolver, not exactly a firewall thing but still unfortunate all the same
use cloudflare's 1.1.1.1 DNS resolver and report back
Solution
Got solved by changing the backend url from railway domain name to ours
Thanks for all the help
