What could be the problem of low openvpn speed?

Question

openvpn

Good afternoon.
I use VPN on the phone and on the PC
On the PC everything works fine
On the phone through "openvpn for Android" it constantly gives tls error local / remote key is out of sync, then it connects and works fine for 10 minutes, then it gives a ton of errors and loads at speed 5 kilobit/second.

Answer 1

Perhaps the reason is in the law of the Russian Federation of 11/01/2017?
How to bypass VPN blocking by ISP?
How to ensure the work of VPN after 11/1/2017?

Answer 2

Perhaps the problem is in the banal compression, the phone does not pull. In general, if you want speed, then turn off compression.
