Cannot add EOIP (action failed (0)

I had an eoip tunnel that worked for years recently I rebooted and the mikrotik lost the EOIP tunnel so I tried to add it again now I am getting Couldn’t add new interface action failed error.

in addition every time I reboot the router it loses the 0.0.0.0/0 default route too ( but the rest of my routes are intact)

this is my main router so I cannot take it down to re configure.

I have v5.20 on rb495G

Please Help.

Thanks
