I've tried to restart the service in Linux a few times, and toggled remote access and seems stuck with the spinning cursor on Requesting HTTP Cert.

Any ideas?

Did you ever figure this out? I have the same issue on Mac.

#3

Please try turning off remote access then re-enable after a minute.

#4

Same thing.

After refreshing the browser it worked, thanks for your help!!

I'm having a similar problem, the remote access link is not working even though it shows no errors in the log. I've tried the suggested work-around of turning it off for a minute or so and enabling it back on. I can confirm port 8090 is reachable from the internet (tested via CanYouSeeMyPort). I did reinstall the server two weeks ago as I was moving to a new server but it hasn't work.

Try turning off the DVR via the Synology apps interface, then back on

#10

Done, but now it's not finding my IP, can you help?

Try my.channelsdvr.net from a phone on LTE. It seems to be set up just fine, and probably your router is not letting it load while you're at home.
