SSL_ERROR_RX_RECORD_TOO_LONG when accessing HTTPS over tailnet

Tailscale version - 1.34.1
Your operating system & version - Synology - Docker

Hi all, I’m trying to set up HTTPS / Certs for tailnet access at

I enabled HTTPS in the admin console, ran docker exec tailscale tailscale cert on that machine. It got the certificates and I can see them at ${TailscaleConfigDir}/var/lib/tailscale/certs

I tried restarting tailscale, but I still get SSL errors when trying to access a service through browser.

Firefox returns SSL_ERROR_RX_RECORD_TOO_LONG, edge/chrome give a generic ERR_SSL_PROTOCOL_ERROR.

I’ve tried searching up and down for a coupled days to resolve this, but having no luck.

Not quite sure where to go from here. Any guidance?
