The solution that worked for me was to configure the rut240 in full-proxy, as suggested by Tomas. You can find his comment here.
The solution is:
1/ Follow the instructions given in scenario 3 of the wiki.
2/ When you reach the section "WireGuard peer Linode," the tutorial tells you to add <10.0.1.1/32> in the field of "Allowed IPs. Instead of doing so, you need to add in the field "Allowed IPs the IP address <0.0.0.0/1> and then click on the plus button and add the IP address <184.108.40.206/1> in the second "Allowed IPs" field.
It took several weeks for me to bring the miner of the relay status. So, be patient.
I hope this will work for you too
All the best
