Check Sync fails on RM2 running 3.24.0.149

[gotgot1995]

Hi,

I accidentally let my reMarkable 2 tablet perform an update to version 3.24.0.149 and it obviously broke the link with my local instance of rmfakecloud. 😢

I tried to follow the online guide Reenabling after a system update. After running the commands, I successfully could pair my device again with my rmfakecloud. However, the sync did not seem to complete anymore: it does not show the sync failure icon, but documents are not updated and the only logging entry that shows up in the rmfakecloud console after timeout is the following:

INFO[0759] [GIN] 2025/12/11 - 21:11:19 | 201 |       92.16µs |      10.11.99.1 | POST     "/analytics/v2/events"

Any help would be greatly appreciated. 🙏

What version of rmfakecloud are you running? What does the logs for the proxy on the device say? Same with the logs for xochitl on the device?

✅ I can't seem to find any error from in journactl -u proxy -l:

⚠️ However, each time I edit and save a notebook, I'm getting these errors in journactl -u xochitl -f:

Also, I noticed that after each reboot:

• ❌ pairing is broken
• ❌ trying to pair again without reenabling after a system update fails and causes the following error in journactl -u xochitl -f:

• ✅ even though, the proxy service is still alive
• ✅ adding 127.0.0.1 webapp-prod.cloud.remarkable.engineering to /etc/hosts seems to fix the pairing after reboot

🤔 After that, I couldn't get any further as I could see a lot more logs without error in the rmfakecloud console than before. But none of my documents are synced, still. Now I'm getting a lot of these:

What version of rmfakecloud are you running?

I think you either forgot to reply to this, or GPT'd it out of your response.

Also, I noticed that after each reboot: ... pairing is broken

Could you expand on this more? You shouldn't need to pair again after a reboot, unless you mean you unpair and try to pair again?

Does the UI show an error when trying to sync after you've paired? Same with when you ran check sync?

Is sync15 set to true for your .userprofile in the rmfakecloud server?

[gotgot1995]

Sorry for the delay in replying. Also, I didn't use GPT to reply. I just focused so much on looking for more logs on my device that I forgot about your first question. Sorry about that. 😬

What version of rmfakecloud are you running?

I'm running rmfakecloud version v0.0.26-22-gdbd23cd. Should I try updating to version v0.0.27 ?

I'll investigate what you suggested and get right back to you.

[Eeems]

It wouldn't hurt to update to the latest.

[gotgot1995]

Does the UI show an error when trying to sync after you've paired? Same with when you ran check sync?

At the moment, still running rmfakecloud in version v0.0.26-22-gdbd23cd, when I go to "settings" then select the "cloud" tab and then click on the "check sync" button, the UI shows "checking sync..." for 30 seconds, and then says "No syncing errors found. If you still experience problems, try restarting your device" even though my notebooks are clearly not synced. Same on the home screen, no error shows when syncing.

I'll update rmfakecloud and try again right away.

[gotgot1995]

Is sync15 set to true for your .userprofile in the rmfakecloud server?

Yes, it is.

Updating to v0.0.27 didn't seem to change much: pairing still works but syncing does nothing except showing the same log in the rmfakecloud output console:

INFO[0268] [GIN] 2025/12/16 - 22:09:05 | 201 |      43.834µs |      10.11.99.1 | POST     "/analytics/v2/events"

What error is shown in the xochitl log when you check sync?

What error is shown in the xochitl log when you check sync?

Here's what shows journalctl -u xochitl -f when I check sync:

And again, it says "No syncing errors found." still... 😕

[Eeems]

Is eu.tectonic.remarkable.com in the /etc/hosts on your device?

[gotgot1995]

It's getting late here so I've already disconnected everything. But from what I remember, that host name was not in the in /etc/hosts file. I'll try to add it tomorrow and check if that solves it.

Thanks again for your time. 🙏

Hi 👋

I tried adding 127.0.0.1 eu.tectonic.remarkable.com to /etc/hosts but it caused the following SSL error in journalctl -u xochitl -f:

You'll need to regenerate the proxy certificate with that host in the list

[gotgot1995]

So, I edited the installer.sh script on my device and added 127.0.0.1 eu.tectonic.remarkable.com to the generate_certificates() function as well as DNS.6 = *.tectonic.remarkable.com to the [ san ] section. Then I ran a ./installer.sh uninstall and ./installer.sh install and now everything works again. 😄
