Error upgrading RT-AC68U from 380.69 to 380.69_2

[Naving]

Hi!

I'm currently running 380.69 on my RT-AC68U.

However, when I try to upgrade to 380.69_2 I get a following error

---
Invalid Firmware Upload

Firmware upgrade unsuccessful. This might result from incorrect image or error transmission, please check the model name RT-AC68U and version of firmware from support site and try again.
---

The checksum of my RT-AC68U_380.69_2.trx is as expected (c1251b1a2facf0dd2920451e5ba0f296e133913a9c199ca4bccaadf0d091f546).

Can you please advise what may be the cause of this issue?

I tried restarting the router, moving the trx file into a different directory and even renaming it. Still no luck. Any other ideas?
