First connection issue: blank screen immediately after connecting to Pydio Cells server

[lispstudent]

Client OS : Windows
Client version: CellsSync - 0.9.2
Revision ad58523 (2020-09-10T09:43:57)
Pydio Server OS: FreeBSD 13.1
Pydio Server version: Pydio Cells Home Edition (v3.0.7), installed from ports

This is a first connection issue.

When I try to create first account:

• I add proper URL to the Pydio Cells instance
• I click on login button
• Cell Sync open my browser, I see this URL:
  http://localhost:3636/servers/external?manager=https://cells.my-domain.in

I briefly see server backdrop, then page becomes blank.

• Browser has page open, logged in to my Pydio account
• Tried with Firefox, Brave, Edge.

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.
No site is currently configured. Cells exposes automatically the following URLs :

Note that Let's Encrypt validation protocol requires a temporary access to port 80.

   Config has been updated, please restart Cells now.

• 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

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)

[lispstudent]

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:

+---+--------------------------+--------------+----------------------+
✔ 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?

[lispstudent]

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