I started a new installation of rancher via the website. (3 servers masters + nodes)
Result: no problems.
For testing reasons, I stopped the rancher/rancher container. (example: take a backup).
Problem:
If I start the container again I got the error:
'''Error response from daemon: driver failed programming external connectivity on endpoint xenodochial_austin (c26c8cea040361b60ced4a51355d67702a0b8fc8062659f6d28719ec77357b3d): Error starting userland proxy: listen tcp 0.0.0.0:443: bind: address already in use
Error: failed to start containers: 2e8a2f659909’’’
How can I start again my rancher/rancher container?
Rem
If you separate the rancher/rancher server (Example RKE installation + 1 external rancher/rancher server) than you can take a backup.
