Unable to claim staked aava

For the last few weeks, i can't claim staked aave rewards. If i connect ledger through Metamask, i get the error "RotationProvider exceeded max number of retries.…". If i connect with ledger directly on v1 aave, i get the error "Transaction failed with the reason: execution reverted: ERC20: insufficient allowance". There is certainly sufficient ETH balance for gas.
