Hi,

I have tried to setup OpenVPN server regarding to this guide: https://www.tp-link.com/us/support/faq/1239/

I'm stuck in the prerequisite step "Generate certificate", after clicking the button a progress bar appears for a while, going to 100% and then message "Failed. Please try again." appears. I have tried several time without success. There's nothing I can see in router's log.

Would anybody know cause of this issue?

Thanks in advance

Premek V.
