[Bug]: Fresh tarbal install doesn't allow (even first) admin login about server HOT 3 CLOSED

but doesn't accept admin login/password

Which does it say precisely? Is it Temporarily Error or is it Wrong username or password or something else?

What does log entry look like in your Nginx access log?

Is this all through http://localhost or something else?

I assume you double-checked in a different browser too, correct?

Can you also check your browser console and browser console network tab for clues?

Also maybe bump your Nextcloud Server loglevel down to 0 (DEBUG level) then restart FPM and reattempt logging in while watching your nextcloud.log?

I know you mentioned you used the documented Nginx config, but just to confirm... You're using the one from the v28 manual and nothing pre-v27 (since the Nginx config was updated), correct?

from server.

Thank you for your prompt reply, I very appreciate such an attention.
In fact I've already found root of the issue (tnx to your advice to deep check browser logs) - just one little thing I missed in nginx site config editing:
fastcgi_param HTTPS on; - changing it to off resolved problem immediately

My NC setup is strictly local, so no need in https/TLS stuff with users frightening self-signed certs.
Unfortunately there is no howto for such cases, despite the phrase "and it is accessed via http(s)://cloud.example.com/" in nginx config docs, no http-only settings. I close this issue as it's obviously not a bug, but leave my answers for those who may bump in similar situation. Thank you again!

Nothing, just reloads login page with empty password field

What does log entry look like in your Nginx access log?

Nothing special, just ordinary requests for img, css and other usual stuff

Is this all through http://localhost or something else?

It's machine in local network, so URL looks like http://ms/index.php/login?clear=1

I assume you double-checked in a different browser too, correct?

For sure: FF, Chrome. Chromium, Opera

Can you also check your browser console and browser console network tab for clues?

That's what worked finally: I noticed warnings like "can't save secure cookie from insecure source" or something like this

I'm not sure how to determine v28, it was only official one I found

Glad you got it worked out!

Unfortunately there is no howto for such cases, despite the phrase "and it is accessed via http(s)://cloud.example.com/" in nginx config docs, no http-only settings.

The full config there includes an http -> https redirect (the first server block). That's that it's referring to I believe.

FYI that link is for Nextcloud v21.

Make sure you're referencing the one from the Admin Manual that matches the version of Nextcloud Server you're using (visit https://docs.nextcloud.com and choose the appropriate version).

We do update the config at times and it's had several critical changes the past couple versions. You'll definitely have some problems using a v21 config with a v28 installation.
