I imagine you tried the 2 button reset as the first resort but it does not sound good. The contacts are spring loaded on the lens side, so inspect them closely to see if the lens/mount contacts are at the proper height.
As a general rule, contacts should not be "cleaned" with any solvent that could remove the film residue on the contacts that helps prevent oxidation. The only "dirt" that contacts need maintenance for is the naturally developing oxidation. It is a good idea to use a tiny amount of a good de-oxidizing agent on connectors once a year or so. The standard of the electronics industry is Caig Laboratories D-5 DeOxit but there are a number of them using the licensed formula from the first one named R-5 Cramolin. That is still available in Europe, as well as CRC 60. In the US, Caig products are used by most recording studios and broadcast for oxidation removal.
Alcohol and anything labeled contact cleaner is probably too drying which increases the rate of oxidation. Some recommend a pencil eraser but that is one of the very worst ways of attempting to clean contacts. The contact might look shiny but its resistance increases because of the tiny scratch marks left in the mating surfaces, leaving more surface area to oxidize and less are for mating with its contact mate.
I really doubt that contacts are staying consistently open for you, with 2 lenses, it is likely something less user serviceable.
