If Pushover has issues, how do get your messages? You rely entirely on a thirdparty service in the cloud.
You do know that this is /r/selfhosted right?
I do use Pushover myself and its great and cheap, but its absolutely not comparable to ntfy or Gotify being selfhosted.
Also with local selfhosting you can still get messages when your internet is down.
EDIT2: the IP of the server is static, and I used the new external IP after the router restart
Why bother with connecting through the IP at all? Do yourself a favor and set up a simple free DDNS for your external IP. Most likely your router can keep it automatically updated, if not plenty of small tools exist for it such as ddclient.
And even better, if you also use SRV records for Teamspeak in your DNS, then you dont even need to specify the port number anymore.
You can turn this 142.16.420.69:56610 into just myteamspeak.dedyn.io and done. Much nicer and easier to tell people to use when they want to join your server.
Try /r/Homelab /r/HomeServer /r/unRAID and such.
Search this sub for "best distro" and "best OS" and such, its been asked and discussed so many times.
Just making sure you read the whole thing...
Check /r/CosmosServer
I dont use it myself beyond being curious about it. But i think its a good choice for beginners to get started with selfhosting the typical things like Pihole and immich. And the dev seems very active.
CasaOS is similar. UmbrelOS is a dumpster fire. Tipi also exists, seems alright. Start9 seems a lot like UmbrelOS, i dont like it at all. Yunohost is kind ot similar to all of these but its a actual OS and it doesnt use Docker to deploy the services.
If you do want to try any of them, imo install and try both Cosmos and Casa (not on the same machine at the same time ffs) and give them a try. Cosmos probably is the best currently but thats of course just a matter of opinion and personal taste.
Plenty of guides exist on how to use Portainer to deploy a compose file.
You can also ask in /r/Portainer for help i guess.
but it doesn't worked
So many details.
Why not use some type of "network info tool" app to find out which DNS servers are actually being used and what their replies are?
Android is well known of often sneaking in the Google DNS servers (8.8.8.8 and 8.8.4.4 for IPv4) if you only enter one DNS server in the network options of your WLAN. Place your own DNS into both fields. Some Android ROMs complain then that they are identical, in that case try to enter 127.0.0.1 or 0.0.0.0 for example as one, if that also doesnt work then just make up another IP that fits your network. It will send requests into nowhere but since the other one is working, it doesnt matter much.
A lot of Android ROMs also have "Private DNS" enabled by default. Disable that, it might be the reason its bypassing your local DNS (Pihole, Adguard Home, whatever).
And some users mistakenly enter their own local DNS (like a Pihole) into the "Private DNS" option.
What is also possible is that some apps have their own builtin "by-pass", for example they might use DNS-over-TLS or DNS-over-HTTPS (DoT/DoH) to make encrypted DNS requests to fixed servers, completely ignoring whatever you set in the OS network config.
/r/Android and /r/HomeNetworking can help.
You cannot find the search option?
Thats not a good excuse imo. And even if ignoring the sidebar, nothing is stopping someone from simply searching "google photos" in the sub and find tons of discussions about this.
Google Photos alternative is the literal example in the subreddit sidebar, and this gets asked so often.
Why dont you simply search this sub?
I shared my very basic and easy setup with Caddy + Authelia some days ago.
If you are deadset on using NPM tho, i find that is harder to share a exact config because its UI based.
In general its a good idea to provide details of how exactly something has failed for you, instead of saying "it has not worked".
Chances are high that someone spends their time and shares and explains their NPM+Authelia config to you, and you run into the exact same problems again and "its not working".
