Please try again later (0x0018)" is displayed. This is happening on numerous systems and has been verified via 4 completely different Internet connections now.

We are currently investigating the issue that is causing the "Video Conferencing service temporarily not available. Please try again later (0x0018)" message to appear.
Thank you. I have tested a few time this morning and it has not happened again, so far. Will keep testing and will let you know if it does happen again @VasilisV_3CX.
Just an update: There was a temporary connectivity issue which has since been resolved and redundancies put in place to avoid this issue occurring again. I will mark this thread as solved. Thank you all for reporting this.
