First connection issue: blank screen immediately after connecting to Pydio Cells server about cells-sync

1 - [8080 instead of 443] Did you Restart after updating the Site ? if you run cells configure sites again, were your modification properly saved?
2 - Once 1 is ok, try to set the External URL (even if no proxy) to https://cells.mmc.re (and restart)

[cdujeu]

Hello, this is generally due to a server Site misconfiguration (TLS Certificate or site External URL).
Do you have a reverse proxy ? (if so make sure to set the External URL).
What TLS config do you use ?
Try opening the localhost:3636 URL in the browser window with the Developer Console open to see if there are any errors displayed

Thank you for the pointers.

I do not have a reverse proxy, unless Pydio Cells is using Caddy as one?

Just to be sure, I have reset the configuration with cells configure sites:

cells configure sites
Warning: no private IP detected for binding broker. Will bind to 157.90.53.130, which may give public access to the broker.

• First issue I met with is that Cells is available at https://cells.mmc.re:8080, but not at https://cells.mmc.re

• If I setup Cells-Sync with login URL: https://cells.mmc.re:8080, I get a Network Error:

GET https://cells.mmc.re:8080/oidc/.well-known/openid-configuration net::ERR_FAILED
404

But Cells server is available at https://cells.mmc.re:8080

Thank you for your help!

1. Yes, I did, twice. Also, I checked again with cells configure sites, the modification was saved.

2. Now I have added the URL, even if not proxied:

********************************************************
   Config has been updated, please restart Cells now.

The following sites are currently defined:
+---+--------------------------+--------------+----------------------+
| # |         BIND(S)          |     TLS      |     EXTERNAL URL     |
+---+--------------------------+--------------+----------------------+

+---+--------------------------+--------------+----------------------+
✔ Quit
root@safe:/ # service cells restart
Stopping cells.
Waiting for PIDS: 12444, 12444.

Still, I can reach Cells via https://cells.mmc.re:8080 but not with https://cells.mmc.re

How can I troubleshot that?

I could not fix my problem, in the meanwhile I will just use ftp. Please feel free to close this issue on your side.
