Hi! Anyone has the problem with staking? I am staking several currencies, but currently having problems with two of them: DMD and another one.

I have about 300 DMD in my wallet, but I have no staking transactions for more than 2 months. I used to have them once in 3 or 4 days earlier. I tried on Linux and Windows using 2 different computers. Firewall is okay. Other cryptos are okay. It might be just a bad luck. However, I would like to ask whether anybody has a similar problem?
