ERROR: broken LATEST file 6.47.7

RouterOS General

Hi together.
I was not able to do an upgrade from 6.44.6 LT online because of timeouts, so I decided to do it manually. After this went well, I wanted to check if I can reach update servers again.
So I did this in Console:

[admin@DE_MIN_SUN_SW_01_01] > system package update check-for-updates 
            channel: long-term
  installed-version: 6.47.7
             status: ERROR: broken LATEST file

[admin@DE_MIN_SUN_SW_01_01] > 
[admin@DE_MIN_SUN_SW_01_01] > system routerboard print 
       routerboard: yes
             model: CRS328-24P-4S+
     serial-number: C7810C2A6B07
     firmware-type: dx3230L
  factory-firmware: 6.44.6
  current-firmware: 6.47.7
  upgrade-firmware: 6.47.7
[admin@DE_MIN_SUN_SW_01_01] >

How can I fix latest? Or how can I see what is writen in latest?

I made a downgrade, now I get timeouts.

[admin@DE_MIN_SUN_SW_01_01] > system routerboard print 
       routerboard: yes

But ping is working

[admin@DE_MIN_SUN_SW_01_01] > ping upgrade.mikrotik.com

What can be a solution for this?
