connection on HTTPS

[plegall]

It seems that Remote Sync can't connect on HTTPS or maybe on HTTPS with self-signed certificate, as described on http://fr.piwigo.org/forum/viewtopic.php?pid=216522#p216522

Tell me if you have a Piwigo behind HTTPS for testing (I should be able to provide one)

Can you start the application like mentioned here please : https://github.com/Piwigo/Piwigo-Java#troubleshooting ?

Is the remote gallery version > 2.6? Because, it was never tested with older versions. Maybe a test of the version would be a good thing.

And finally, yes a HTTPS gallery would be useful.

It seems to work with HTTPS. But I must investigate with self signed certificates.

I can add an option to ignore SSL certificate problems, and just log a warning instead of throwing an Exception.

I've just set up a Let's Encrypt certificate on my test site - https://test.orrison.com/piwigo, and am getting an error:
[ERROR] Unable to connect : SSL certificate exception (Please use option 'Trust SSL certificates') [ERROR] Error in sync

This isn't a self-signed certificate, but I tried ticking the "Trust self signed SSL certificates" option anyway, but it didn't help.

(That's perhaps a separate bug: the error message says "Please use option 'Trust SSL certificates'" but the option is actually "Trust self signed SSL certificates".)

I'd be happy to set up a login for you on that test site.

I have been using the remote sync on this site for some time, without any problems until I installed the certificate. I'm on Piwigo 2.7.4, and I think the latest Remote Sync (it doesn't show a version number).

Also perhaps significant: I've turned on rewriting from http: to https: and Strict-Transport-Security.

Java debug log attached: remotesync-log.txt

Final update for this test case: Java (current version 8 Update 73 on Windows) doesn't include the necessary root certificates for Let's Encrypt, so it looks like a Java problem. It is possible to add root certificates to Java.

Another test case: https://orrison.com/test/piwigo works ok, using a certificate issued by Comodo.

Can you try again the trust ssl certificates option?

[rorrison]

It is now connecting fine on my test site with a Let's Encrypt certificate. Using v0.0.13 and Java version 8 update 101 (update 101 included the root certificate used by Let's Encrypt).
It works with and without the "Trust SSL certificates" option.

Can you make the same test with an older java version?

Hello @rorrison,

Thank you for reporting this to us.
As Java 7 is now the minimal requirement for using this tool, this should cause no problems with the SSL certificates.

Have a great day !
