Adsense RPM drop 50% after migrating website: seen this before?

Our Adsense RPM dropped 50%+ after migrating from a shared VPS to a dedicated server.

Has anyone seen this before? Any ideas how to fix it?

Only idea is that since our IP address changed, Adsense reset our advertisers, or that the old shared VPS server was connected to higher RPMs compared to the new machine running a dedicated server.

Any advice is appreciated,

It has nothing to with servers, check your traffic levels, check if ads are working or no

Same traffic levels, ads working the same, the drop happened the exact day of the server migration when our IP changed.

Was 1.5 years of steady RPM, then for the past 6 months since the migration they've been around 50% of previous levels (happened 3 months before the pandemic)

Try another ad network like mediavine, adthrive, monumetric etc.
