TAILMON TAILMON v1.1.1 -Jul 26, 2025- WireGuard-based Tailscale Installer, Configurator and Monitor (Now available in AMTM!)

Thanks this worked!

Just for the record, v1.86.0 seems to work OK for me getting to my router/devices behind my router from remote.

@rung ... you can also downgrade this way:

tailscale update --version 1.84.0

Unfortunately, this command didn't let you downgrade only upgrade. I successfully used Colin's method.

However, I found the version was not the issue but I did fix it somehow:
1) downgrade by copying the binaries then restarting tailscale in tailmon. Saw a warning about mismatched versions so I restarted twice
2) Found issue still existed
3) Unsuccessfully tried to upgrade in tailmon. An error about some cache directory being readonly
4) Completely shutdown tailmon and then restarted tailmon
5) Upgrade now worked in tailmon with same warning about a mismatch.
6) Can't remember, may have restarted tailscale again here

Now it works again! No idea what was wrong before.

Thanks,
Rung

Looks like that feature may be broken... but according to the docs, it should be possible:

Glad things are back up and running again!

Small patch to help with some message rate limitations in the situation of a network outage, as reported by @JGrana. Thank you!

What's new?
v1.1.1 - (July 26, 2025)
- PATCH: Modified a section of code that checks to see if the Tailscale service is dead, and tries to restart the service. @JGrana found that in a case of a network outage, that TAILMON will flood you with messages indicating that it tried restarting the service, only to have it loop until network connectivity is restored. This puts a rate limiter on to only attempt this every 60 seconds. It will also execute a fresh version of the script each time to eliminate any factors around that.
