Hello Gediminas,
Thank you for your question about this item. We investigated to see what we encountered when we placed the snipe for you.
eBay suddenly is rejecting your bids because you still have outstanding steps to take in regard to verifying your identity. eBay limits the number of items you can bid on (with a third party) until you complete authorization steps, so make sure that you have set up 2-factor verification at eBay and done the phone verification. This is new thing eBay is phasing in and we are writing an announcement for it.
I hope this answers your question. Please let us know if we can provide any more information.
