Soon after the installation, I’m not able to connect. Here is the error. It’s about about a 502 to the auth’ connector internal service… but why, and how to further debug and resolve this? As shown by the cfuid cookie in the client request, the server is behind a Cloudflare proxy. The redacted hexadecimal IP address is the actual public address of the VPS. ```auto [...] Failed to initialize OIDC server: server: no connectors specified 2020-02-20T18:22:38.269Z DEBUG pydio.web.auth Config {"config": {"dex":{"issuer":"https://my.domain.com/auth/dex","staticClients":[{"Id":"cells-front","IdTokensExpiry":"10m","Name":"cells-front","OfflineSessionsSliding":true,"RedirectURIs":["https://my.domain.com/login/callback"],"RefreshTokensExpiry":"30m","Secret":"iZxcyMidSFFuuVEM7Ku3UItR"}],"web":{"http":"https://my.domain.com/auth/dex"}}}} Failed to initialize OIDC server: server: no connectors specified 2020-02-20T18:22:39.180Z DEBUG pydio.rest.frontend JWTHttpHandler: Checking JWT 2020-02-20T18:22:39.180Z DEBUG pydio.rest.frontend No Claims Found {"ctx": "context.Background.WithValue(&http.contextKey{name:\"http-server\"}, &http.Server{Addr:\"\", Handler:(*http.ServeMux)(0xc0030a4d80), TLSConfig:(*tls.Config)(0xc0090ae780), ReadTimeout:0, ReadHeaderTimeout:0, WriteTimeout:0, IdleTimeout:0, MaxHeaderBytes:0, TLSNextProto:map[string]func(*http.Server, *tls.Conn, http.Handler){\"h2\":(func(*http.Server, *tls.Conn, http.Handler))(0x1c99f80)}, ConnState:(func(net.Conn, http.ConnState))(nil), ErrorLog:(*log.Logger)(nil), disableKeepAlives:0, inShutdown:0, nextProtoOnce:sync.Once{m:sync.Mutex{state:0, sema:0x0}, done:0x1}, nextProtoErr:error(nil), mu:sync.Mutex{state:0, sema:0x0}, listeners:map[*net.Listener]struct {}{(*net.Listener)(0xc00a760100):struct {}{}}, activeConn:map[*http.conn]struct {}{(*http.conn)(0xc009cc2fa0):struct {}{}}, doneChan:(chan struct {})(nil), onShutdown:[]func(){(func())(0x1ca93a0)}}).WithValue(&http.contextKey{name:\"local-addr\"}, &net.TCPAddr{IP:net.IP{XXXXXX}, Port:40347, Zone:\"\"}).WithCancel.WithCancel.WithValue(4, \"pydio.rest.frontend\").WithValue(3, 0x20).WithValue(8, config.Map(nil)).WithValue(metadata.metaKey{}, metadata.Metadata{\"ClientTime\":\"2020-02-20T18:22+0000\", \"ContentType\":\"application/json\", \"CookiesString\":\"pydio=MTU4MjIyMjAyMXxEdi1CQkFFQ180SUFBUkFCRUFBQUJQLUNBQUE9fB3rZYPFLDSg290AOCgMZezFVxY7quMkvPHXqECy5kV-//__cfduid=d7cbdf51ea3d0bdca613e1df377a86b111572639992//_gcl_au=1.1.131278179.1574864160//_fbp=fb.1.1575491962426.921951848\", \"HttpMetaExtracted\":\"HttpMetaExtracted\", \"HttpProtocol\":\"HTTP/1.1\", \"RemoteAddress\":\"XXXXX\", \"RequestMethod\":\"POST\", \"RequestURI\":\"/frontend/session\", \"ServerTime\":\"2020-02-20T18:22+0000\", \"UserAgent\":\"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:73.0) Gecko/20100101 Firefox/73.0\"}).WithValue(metadata.metaKey{}, metadata.Metadata{\"ClientTime\":\"2020-02-20T18:22+0000\", \"ContentType\":\"application/json\", \"CookiesString\":\"pydio=MTU4MjIyMjAyMXxEdi1CQkFFQ180SUFBUkFCRUFBQUJQLUNBQUE9fB3rZYPFLDSg290AOCgMZezFVxY7quMkvPHXqECy5kV-//__cfduid=d7cbdf51ea3d0bdca613e1df377a86b111572639992//_gcl_au=1.1.131278179.1574864160//_fbp=fb.1.1575491962426.921951848\", \"HttpMetaExtracted\":\"HttpMetaExtracted\", \"HttpProtocol\":\"HTTP/1.1\", \"RemoteAddress\":\"XXXXX\", \"RequestMethod\":\"POST\", \"RequestURI\":\"/frontend/session\", \"ServerTime\":\"2020-02-20T18:22+0000\", \"UserAgent\":\"Mozilla/5.0 Firefox/73.0\", \"x-pydio-span-id\":\"f9e116ec-540d-11ea-88a0-fa163ee72a12\"}).WithValue(servicecontext.spanContextKey{}, &servicecontext.Span{SpanId:\"f9e116ec-540d-11ea-88a0-fa163ee72a12\", ParentId:\"\", RootParentId:\"\"})"} 2020-02-20T18:22:39.281Z DEBUG pydio.web.auth Config {"config": {"dex":{"issuer":"https://my.domain.com/auth/dex","staticClients":[{"Id":"cells-front","IdTokensExpiry":"10m","Name":"cells-front","OfflineSessionsSliding":true,"RedirectURIs":["https://my.domain.com/login/callback"],"RefreshTokensExpiry":"30m","Secret":"XXXXXXXXXXXXXX"}],"web":{"http":"https://my.domain.com/auth/dex"}}}} Failed to initialize OIDC server: server: no connectors specified 2020-02-20T18:22:39.383Z ERROR pydio.rest.frontend Got a 502 when contacting gateway -

The corresponding sourcecode at > shows that it’s a kind of “error catch-all”. I think clearer error message could help to tackle it. For example : Which URL has been requested, what was the returned HTTP code? And the body? ---

I tried the installation yet another time. This time I’m seeing this: `jwt rawIdToken verify: failed {"error": "oidc: expected audience \"example-app\" got [\"cells-front\"]"}` that keeps me from connecting as an `admin` after the installation. I don’t know if it’s tightly related, but still, worth mentioning here I think. Helpful command: `# ./go/bin/bbolt page-item --format bytes --value-only ./.config/pydio/cells/configs-versions.db 9 1 | jq '.Data.services["pydio.grpc.auth"].dex.staticClients' ` (`boltbrowser` is helpful too) /edit: Sounds like after stopping the `cells install` and running `cells start` afterwards I was finally able to connect (!) Note: `configs-versions.db` (latest version!) does not contain the above `example-app` anymore. ---

I’m getting this problem again, but just for `cells start` this time (!) `auth/dex/` always returns 502 what keeps authentication from working. `cells` boot is **stuck in a loop** with generated caddy configuration always showing `auth/dex` as PENDING. I tried to restore previous configuration, mysql dumps, … (but I’m always getting `Configs upgrades applied` which forcefully set `services/pydio.grpc.auth/dex/issuer` and `services/pydio.grpc.auth/dex/web/http` to `https://domainorg:443/auth/dex`). I feel like this may be somehow related to my problem. I use to have a 2.0.5 which works. I ran 2.0.7 / 2.1.0-rc1 (which failed to work), but even after trying to rollback, I can’t get `cells` to boot anymore. ---

Indeed, if you upgrade to 2.1 you cannot downgrade, you’ll have to re-install ---

Ouch… Reinstalling means losing configuration (users, …), it also means losing encryption keys what means loosing files. But in my case, 2.1.0-rc1 errors out some Go stacktrace which means that _it was a bad idea to try it on a live system_… and that I’ve to downgrade. Why a combination of `config restore`+ mysql dump restoration wouldn’t make a successful downgrade? (I tried but still have the above error) ---

Hopefully, I got 2.1.0-rc2 to work! ---

@charles Hi Charles, I had cells configured and running in a docker container for a few months. I don’t recall if this the first restart of this container since it was set up or not but upon cells is throwing the error “Failed to initialize OIDC server: server: no connectors specified” The first instance of the error occurs after pydio.gateway.data is started and continues to pop-up from there intermittently until this appears to be the last remaining issue. It continues to try to initialize the OIDC server with period restart of pydio.gateway.proxy Do you have any pointers on what I can spot check to rectify?
