We have not changed plate solve validation for a long time and it is an important safety feature.
I don’t really have enough context to speak directly to your issue, but the hint data you passed to the solver was simply too far away from the actual solve and, because of this, was considered suspect.
RA: 0.71 hrs; DEC: 41.32 deg
RA: 23.14 hrs; 41.31 deg
That is a pretty significant difference in RA (1.5 hrs)…
There may be a better way to do this, but turning off the validation is likely not a viable option. This check has been around for more than a year and has protected against many gear damaging slews. If it’s suddenly affecting you it points to change in other areas. One question to ask is why does your mount think it’s pointed more than 1.5 hrs away from it’s actual position when the centering process begins?
