Hello again everyone

Please let me know if my posting here is becoming too regular

I tried out the options suggested by you in the last post. I actually got it working which was a really exciting moment for me. I got home from work and starting trying to set up an authentication that only allows my email to get through and ended up getting a Error 1033, i tried to change DNS settings and then got Error 1016.

I tried restarting my browser, restarting my cloudflared instance on my machine but nothing worked at all.

In short, im very lost. Ive tried following along with afew youtube tutorials but it hasnt really worked. Feeling very defeated, this is way above my knowledge level, but hey, i guess everything ive learnt on this selfhosting journey was once way above my knowledge level so theres always time to learn.

If anyone could point me in the right direction that would be appriciated

I also had a question, do you create a new tunnel for each application? Or do you just use a separate route and have them all on the same tunnel?

Hey there. I don't have anything to say which is actually helpful. I'm just here to say that you are throwing yourself into the deep end a bit since authentication / access control is actually one of the more advanced topics there is.

Once you do get it figured out, you'll look back and it'll make sense. I don't use Cloudflare services for my projects, so I can't actually help you. Auth/access control settings vary highly depending on what you chose to use (cloudflare, tailscale, netbird, etc),

Having skimmed over the other guy's PDF, I'll say that where Cloudflare provides instructions, follow those over his steps 1 and 5 (since if anything will be outdated and not work/no longer recommended, those would be it), but I otherwise don't have complaints. As with everything computers, everyone has their own way of doing things which they insist is the correct way. I'd do things very differently, but I also won't say there's anything wrong with their way.

follow those over his steps

Also doesn't help that Cloudflare moves things around regularly so when you learn a route to what you want to do, it's inevitable changed.

[–] irmadlad@lemmy.world 2 points 2 weeks ago

I feel that.

Very much in the same vein as Azure.

Ha! I commiserate with you. My eyes started to glaze over after a bit. Here are some notes that may help out. They have changed the site around several times so, things may not be exactly in the place as documented, so you might end up hunting around the site. But, this should get you down the road a piece. Additionally, I am running Ubuntu Jammy, so their may be slight differences, I'm not sure.

What exactly is it that you're trying to achieve?

[–] TrippinMallard@lemmy.ml 2 points 2 weeks ago

Try out Netbird reverse proxy. You can connect your domain to a self hosted apps on your netbird mesh.

If it helps, you can think of the cloudflare tunnel as analogous to a VPN. You don't need separate tunnels unless the services involved can't communicate with each other; if they can route to each other already, they should all be discoverable from the tunnel.

It sounds like 1016 and 1033 are both DNS errors, or other connectivity. Your tunnel was up before; it sounds like restricting to just email night have blocked something it shouldn't. How did you block it? Cloudflared needs specific ports open, so if you blocked ports, that might be the issue
