move Nginx proxy manager to new proxmox then get 502 bad gateway

[yingkhun]

Hi I'm new here

I have installed ct turnkey-core and installed nginx proxy manager by docker

docker run -d \
--restart=always \
--name=nginx-proxy-manager \
-p 1280:80 \
-p 1281:81 \
-p 12443:443 \
-v /docker/nginx-proxy-manager/data:/data \
-v /docker/nginx-proxy-manager/letsencrypt:/etc/letsencrypt \
jc21/nginx-proxy-manager:latest

that work perfectly! and I have backup and restore to new proxmox my ct turnkey-core and nginx proxy manager can be run
but proxy hosts I created before not working its have error 502 bad gateway how to fix it?

ps. I move back restore to old proxmox my proxy hosts still work

thank you and sorry about bad in english
