Railway deployment with custom domain doesn't resolve? ERR_TOO_MANY_REDIRECTS

[sai-sy]

Hello! I've been enjoying mathesar and decided to deploy it for a project. I've done the one click railway deployment, set the CNAME to the railway link in my cloudflare DNS, and have confirmed the domain (data.example.com) is the environment variable in Railway, yet I still get an error when trying to navigate to my site. For context I have the standard cloudflare redirects and a redirect for my root domain somewhere else:

I'll poke around Railway today and see what I can figure out for you.

Thanks! I found this resource https://developers.cloudflare.com/ssl/troubleshooting/too-many-redirects/ but at a glance I don't see why. My redirects seem linear. I'm OOO so can't look more closely into it off my phone but, might be the culprit.

The documentation talks about increasing the encryption mode to "Full" to keep the http > https redirect but then asks for an SSL certificate configured.

Changing the encryption mode in cloudfalre from flexible to full worked to solve the ERR_TOO_MANY_REDIRECTS issue as per the docs but now I get a 400 bad request error. Here's my env variables in railway:

@sai-sy, try adding a space between the values in ALLOWED_HOSTS, like domain1, domain2 and I think that will fix the issue!

Thanks @zackkrida that worked. Weird because the docs doesn't specify that and kind of looks as though it's otherwise. Railway also auto filled these environment variables so depending on how railway provided environment variables work either the railway deployment could be changed or just the docs. Thanks for the help!

[zackkrida]

I'll get the documentation updated to fix this, along with the Railway template itself, which we manage and will fix the "auto fill" issue you described. Apologies again for the trouble and I'm glad it's working!

@zackkrida hey zack thanks for the help on this. has there been an issue raised on this as I recently redeployed through railway and ran into the same issue

[zackkrida]

Hmm, I think maybe we're missing something here and there's some other behavior causing the issue. I'm going to debug this a bit this week and get back to you, @sai-sy!
