JOSM ERROR : Unable to retrieve WMS layers list

[SiiG]

Hi,

I desperately try to use a WMS stream published with the SiiG's VMap under JOSM.
This is the feed ​https://carto.siig.fr/wms/public/FluxPublic? which will allow us to display the track sections and address points in order to update OSM.
When I click the "Get Layers" button, I end up with the following error (see screenshot below):

"Unable to retrieve WMS layers list"

I saw that OSM had to have permission to use the service ​https://carto.siig.fr/wms/public/FluxPublic? but I don’t see what to do if that’s the error!

I would like to point out that I have tested the service under QGis and it works well.

Thanks for your help.

My JOSM version is 16812.
My JAVA version is 1.8.0_261.

I received a security warning due to an invalid certificate from that site. After clicking continue it worked for me. Did you receive the warning too?

[SiiG]

Thank you
Not at all.
I get an error message showing a "Validate" button.
When I click on this button I can't get the list of layers and I can't click on the "Validate" button in the "Add an imagery provider" window.

[SiiG]

I forgot to specify that I'm not received a security warning due to an invalid certificate from my site.

[SiiG]

Help me please,
Does anyone have a solution to my problem?
Is there a log file that contains the error that occurs while loading WMS layers under JSM?
Thank you in advance

[SiiG]

I specify that the WMS flow works correctly under QGis (see screenshot attached)

I suggest to start JOSM from a command line with the --debug option. If you can't find a hint there attach your status report and the debug messages here.

I have an "josm.exe" file in "C:\Program Files (x86)\JOSM\" folder.
I also have an "josm-tested.jar" in this folder.
When i start JOSM with this command line "java -jar josm-tested.jar --debug", i get this error message :

Error: opening registry key 'Software\JavaSoft\Java Runtime Environment'
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.

See JavaTest. OP seems to be windows?

Thanks but what do you mean ?
I do not understand "OP"?!?

[stoecker]

The certificate chain is incomplete, so that JOSM wont accept the cert.

There are two possibilities:

• Contact admins to fix the certificate chain: see ​https://www.ssllabs.com/ssltest/analyze.html?d=carto.siig.fr They need to add the missing intermediate cert to the chain
• Simply use http: instead of https:

[SiiG]

OK
Thank you for your answer
We will try to complete our certificate

[SiiG]

Hi,
We installed the intermediate certificate on our server and everything is working fine now.
Thank you very much for the help you have given us.
