Yes tried with wifi and mobile connection.

Made a Jaxx support ticket and they told me not to mine on a Jaxx wallet and to take the private keys and make a new Jaxx wallet and sweep.
I was able to successfully claim more ZEC but I am now having problems with one private key with the most ZEC I have.. keeps saying transaction failed once again.

going to try Coinomi on an IPhone, it seems like a lot of people are having these similar issues on Android according to research.

Never experience issue about coinomi wallet I can receive zec daily from my miner without any error and I can send my zec to other wallets just make sure when sending your ZEC coin to exchanges make sure don't send them all because the remaining will automatically be paying the transaction fees.

Let me know if what phone model and android version your phone have? And let me know if where you live because there are some country that cryptocurrencies are blocked from internet providers.

If the issue is the same as in jaxx wallet it must be your internet connection and firewall. Could you try to reset your router or reboot your internet connection and try again.
