[Infinitysl]

Hello everyone,
if we try to pres over "start now" button of video meeting from some time we get error - "video conferencing service temporarily not available please try later (0x0018)".
I search for some fix or any explanation but find only one on forum ( https://www.3cx.com/community/threa...vailable-please-try-again-later-0x0018.82707/ )
My server is
Linux 10 original ISO from 3cx

Version Number: 18.0 (Build 20)
Number of Simult. Calls: 32
Meeting Seats: 250
License status: Activated

Hello @Infinitysl , this error means that your PBX is not able to contact Webmeeting server https://wmr.3cx.net.
Please check Webmeeting logs on your PBX and look for errors.

Hello, it seems that you are experiencing an intermittent timeout issue on your PBX while contacting wmr.3cx.net. I contacted you privately for more details about your PBX, so we can troubleshoot properly.

 

[Infinitysl]

As you suggested, after restarting network no change, after restarting PBX server the error disappeared and everything works.

 

[MarcelloV]

The customer has a VPN for the VoIP provider, running on the PBX server. This seems to interfere with normal PBX network operations. We suggest following these directions to ensure that 3CX WebMeeting will work properly:

Problem solved!
Thanks for the quick replies and additional information.
Your suggestion to restart solved the problem.
