Paths of Glory. Many occurences of connection loss

Good day. I am very sorry to disturb You but I need Your help a lot, please, help me!

I was playing Paths of Glory module with my friend today two times. When we were playing, we were saddened a lot by connection losses. Let me describe what was happenening in points:

  1. This happened today. We began this game earlier, but we didnt have these problems previous time 2 weeks ago.
  2. At first time we played i used Windows on HDD. On the second time i removed that windows and used earlied installed SSD windows instead.
  3. Dont remember how it was earlier, but today i used 3.6.11 Vassal version, he - 3.6.9 version until the moment i will describe below. Both modules were 10.5.

Now directly to problems we faced:
4. Firstly, it was very difficult for us to start a game. I created a room, he joined and didnt receive information (although i saw “Sending game info” sentence).
5. When we were playing, we faced really many times situation when i was making a move in the game, but my friend told me that he hasnt seen any changes.
6. To solve this we were trying really lot of stuff. We leaved-joined rooms, we pressed “Synchronise” again and again, turned off-on vassal, but game information only after large amount of attempts “agreed” to be sent. As display of the problem, You can try to open Paths of Glory module, go to Server status and watch for Last 24 hours/Last week/Last Month. Youll see plenty of rooms with us (Vitaly820 and Golden age). V&V, Vi & Vi, DoubleV, War, Last. We arent into spamming, we did it just during these hardships to make the game working again.
7. Also what game “loved to do” is to give me “Lost of connection” errors. After which we again faced hardships of synchronising ourselves.
8. There were also many occurences when i couldnt leave the room and go to main room. When i pressed “Join room” at main room, nothing happened. Then i disconnected - reconnected - and my inactive clones remained at the lobby. It was common situation today when in the same room there were 2 Vitaly820. Or 2 rooms with same players, one room is dead, another is alive or struggling to continue the game.
9. At some moment i asked my friend to update vassal client to last 3.6.11 version. He did it, but it profit is doubtful. Since he had updated, i created the room - and again he had troubles with receiving game info from me. Moreover 2 or 3 times after the update it happened that i made move which he didnt see, at least one time followed by disconnect. And then game itself 4 times re-ordered info.
10. If You suppose we had troubles with Internet - when we were playing, we also talked via Discord. Discord hasnt stopped working a single time. When we had out-of-syncs or disconnects, we still communicated via Discord what means that Internet was working.

I will also attach Error Log.

Please, help us! I planned to play with Vassal tomorrow, although with other 2 people, and i hope a lot that this wont occur anymore. What could it mean? What could we do to make this occurences impossible?

Thank You very-very much in advance!

My OS is Windows 10 Home
