Archive.ph requires the use of EDNS extension by your DNS resolver, which passes your IP address on to the remote server. Cloudflare doesn't support that. If you run a pihole or other resolver (or have access to your hosts file/not on unrooted mobile device) you can probably set the address manually to 193.233.203.196
$ dig +short archive.ph @1.1.1.1

I've been using Jerboa and Liftoff Android clients for Lemmy, and Liftoff has been giving me server errors despite the post or comment going through correctly. My last few posts duplicated several times as well, because I kept hitting submit.
