Nobody knows until it's checked out.
I am reminded of the song "Fishin' in the Dark", which is what I am doing, mas o menos .
If it's some glitch in the local uplink, alignment of dish shrinks to almost nothing as a possible cause. My theory holds water only if the locals are on a sat with a location that just got lost due to a Carrier Pigeon striking the dish....
Just because I had similar issues doesn't mean it's the problem this time.
Verify the basics and then proceed.
