I can not access my DVR remotely via a PC or via the apps. I get a message that says cannot connect to your DVR right now, try again later. It has been like this for weeks. I called tech and they reset all the boxes, the ONT, I removed the COAX etc. rebooted and cleared router. The box can be seen online though just not the DVR. Also, on screen caller id does not work and the fix application does not fix it either.
Happens to me every couple months - as does the Caller ID not working, which I see from another thread is happening to you also. My suggestion to you is follow the link below and post the problem there. Those guys always get it working again for me. Why it keeps happening every couple months has never been solved however.
I either have to unplug the DVR or have Verizon send a reboot signal. Even that doesn't work every time. It is a really annoying and inconvenient problem.
