Ring wired doorbell not getting enough power.

Hi, I have the wired version and it has been installed for about a year and working fine.  Now, it keeps showing as not connected on the app and the blue light around the doorbell has about a 1/4 of it blinking and rotates around over time.   The router shows the ring as being connected.  I have not changed anything with the wiring. Any ideas on what the issue is? TIA
