MPPT 75/15 solar controller fault

Hi i have a MPPT 75/15 solar controller, it’s controlled of my phone I noticed it hasn’t been charging my battery for 6 days and it has a flashing blue light, I’ve checked the fuse and the cables to the battery, and I’ve also tested the solar side and I’m getting voltage, any ideas what the problem would be? Thanks.

What is the PV voltage and battery voltage?
Can you give us some screenshots of VictronConnect?
