I have an instance (mander.xyz) for which the database was deleted, and I have set up a fresh new instance at the same domain.
Federation appears to still be enabled with lemmy.ml, but I am having general issues fetching and interacting.
For example, if I try to access https://firstname.lastname@example.org, the error log shows:
2021-12-11T17:53:52.201426Z ERROR lemmy_websocket::handlers: Error during message handling error sending request for url (https://lemmy.ml/.well-known/webfinger?resource=acct:email@example.com): error trying to connect: dns error: failed to lookup address information: Try again
I [posted a somewhat related issue on GitHub ](https://github.com/LemmyNet/lemmy/issues/1986), and it was pointed out by dessalines that "An activitypub actor id must be unique, and you recreated one with new public and private keys". It is not clear to me whether these ids apply only to specific usernames, or if the actor is a more general concept (community, post, instance as a whole) to the point that federation is irreversibly broken.
Are there steps I can take to fix the federation? Or is starting a new instance using a different domain the only way forward to re-enable federation?
I do want to point out that during certain periods of the day federation suddenly appears to work just fine for a few minutes.
I am having trouble getting thumbnails from external websites (such as from youtube videos) to show up in my instance.
Originally I built the docker image using the default iframely.config.local.js configuration file, using:
// For embeds that require render, baseAppUrl will be used as the host.
// Or just skip built-in renders altogether
In an attempt to fix the thumbnails, I have changed this to false, and ran docker-compose down/up, but nothing changed.
Should this be enough to change the settings of the config file? Or should I completely remove the docker images and re-make them?
This approach did not work, and I am having problems trying to identify the root cause.
I have decided self-host an instance as a little side project because I really like the concept of lemmy.
I am a scientist by profession and a naturalist basically since birth, so I have decided nature and science to be the focus of my instance.
The website is https://mander.xyz
I have enabled open federation, so if anyone wants to federate, let's do it! The more the merrier :-)
EDIT: I decided today to rent a small VM server to host the instance, rather than hosting it from my home computer. So it should remain stable.
I am trying to setup an instance, and I have no experience with Docker or web development.
I have followed [these instructions](https://join.lemmy.ml/docs/en/administration/install_docker.html) and managed to setup the default instance without issue (nice instructions, by the way).
I am now trying to follow the [Theming Guide](https://join.lemmy.ml/docs/en/client_development/theming.html), and trying to make some small modifications. I have looked at the source of lemmy-ui and I understand how to make the changes that I want. However, since I am not familiar with Docker, I am not sure about how to build an image for the slightly modified lemmy-ui.
From my current understanding I think that if I want to make any changes to the source, I will have to build from source using [these](https://lemmy.ca/post/1066) instructions. Is this correct?
These past weeks have been especially violent in Myanmar, with many protesters and non-protesters being tortured and murdered in the streets by the Junta..
In your opinion, how should the US government intervene, if at all?
I am learning the very basics of networking and I am trying to set up a simple Tor Bridge node in my home pc (Arch Linux). I have set ORPort to 443, and set up port-forwarding from 443 -> 443. I set the bandwidth limit to 30 MB/s, and bursts of 35 MB/s, and set the Bridge option. I start tor using ‘sudo systemctl start tor’, and use nyx to monitor traffic.
In the connections menu I can see that I am part of several circuits (6 at the moment), and I have seen a few inbound and outbound connections show up. The Download and Upload bar charts just show a few spikes of < 1 KB/sec. The only notices that I have are “Self-testing indicates your ORPort is reachable from the outside. Publishing server description” and “Performing bandwidth self-test… done.” I have left the server running over night but I do not see any improvement.
Is this normal for a new Bridge node, or have I likely configured something improperly? I have tested completely shutting off the router’s firewall and it made no difference.
