Upgrade to latest on 2021.04.12 broke upstream generation

Just upgraded to latest (from the latest of approx last week). Now the reverse proxy template seems to no longer generated correctly. After a quick inspection I see nginx -s reload is fired and failing. Inspection of the conf.d/default file reveals that the upstream sections are no longer populated at all.

Any ideas?

//EDIT: Currently looking if maybe the docker update to 20.10.5 is to blame as I don’t see any changes in the repo that should affect generation. // EDIT2: Manually filling in the server blocks restored connectivity

@megamaced does nginxproxy/nginx-proxy:1586 works for you too ?

[ingwinlu]

@ingwinlu could you try nginxproxy/nginx-proxy:1586 ?

works like a charm:

# heroicdebugging.biz
upstream heroicdebugging.biz {
                                ## Can be connected with "bridge" network
                        # nginx_www
                        server 172.17.0.3:80;
}

Feel free to close the issue once its generally available.
