My previous career was as a
licensed journeyman & master
electrician & electrical contractor.

You can’t troubleshoot over
the internet.

You need the serving local
utility company to come
out - pull your electric meter
and check the line side voltage.

Coordinate this with a visit at
the same time with a licensed
electrical contractor to inspect
the meter socket for loose connections
and/or arcing & burning at the
wire terminations and/or bends
in the wire that could have nicked
the wire insulation.

From the point of service entrance
you need to trace the feeders and
neutral back at every junction box
and termination point.
