Failed to initialize OIDC server: server: no connectors specified

drzraf · February 20, 2020, 6:32pm

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.

		if err != nil {
			if strings.Contains(err.Error(), "502") {

	wrapped := servicecontext.HttpMetaExtractorWrapper(dexServer)
	wrapped = servicecontext.HttpSpanHandlerWrapper(wrapped)
	wrapped = service.NewLogHttpHandlerWrapper(wrapped, servicecontext.GetServiceName(pydioSrvContext), servicecontext.GetServiceColor(pydioSrvContext))


	if c.Web.HTTP != "" {
		logger.Infof("Listening (http) on %s", c.Web.HTTP)

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.

drzraf · June 23, 2020, 4:04pm

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

drzraf · June 24, 2020, 1:20pm

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)

drzraf · June 26, 2020, 3:36pm

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?
