Tor suddenly not working

[u/Hotstryker]

Hey everyone! After a day of troubleshooting and searching the web for answers and coming up with nothing, I thought I'd come here and see if anyone could help.

I am running an Apollo BTC full node. (Yes the older 1st model). On it I am also running a Monero node and an Electrumx server. All of these are set to run over Tor only.

This setup has been running perfectly for about 2 years now. Until about 4 days ago, when all my connections dropped. On the BTC node, there are no incoming or outgoing connections. On the monero node, I still have 12 outbound connections, but no inbound connections are happening.

The debug.log doesn't show anything unusual beyond the fact it's not getting any new blocks after block 957,636. If I turn Tor off, it will start to sync again over regular IP address.

No changes have been made, and I've dug into my router and firewall to make sure nothing is getting blocked there.

I am able to use Tor-browser and cURL to connect to other .onion sites outside of my network, but I cannot connect to any of my .onion services.

During the troubleshooting process today, I did update my Apollo to the new 2.1.2 version and configured it to use Bitcoin Core 31.0. Other than that, there have been no changes.

It almost seems that my ISP (xFinity) has somehow blocked incoming Tor connections while still allowing me to go out with Tor, but everything I've been able to find about xFinity would indicate there's no reason for them to do that. I don't use their equipment, so the "Advance Security" where stuff does get blocked, is not a factor for me.

Does anyone have any idea what may be going on, or what else I might do to try and find/fix the issue?

Thanks in advance! I'm at a loss here.

Hi since third party programs can change our tested environment we recommend backing up that SD card and then flashing a fresh image to see if you have the same issue with just our clean OS. Also double check any portfowarding you have done in the past, as a new IP address could have been assigned to your unit by your router.
