Unable to GIN Transaction Pending State - Connection Interrupts - WebSocket Issue

[reasje]

Users are experiencing issues where transactions are unable to reach the 'Pending' state, likely due to connection interruptions. This appears to be related to WebSocket connectivity problems.

I have tested these cases, Applied some improvements but there are factors that might still cause the issue, If you experience any issues, It would be great If you can report steps (Even intermittent), With exported logs, So that I can have closer look.
Scenarios that I didn't get any issues on latest build:

• Changing chains
• Switching accounts
• Internet disconnect (Full disconnection)

Sang still faced this issue,
I checked websocket handling
We are doing our best to handle connection interuption on this matter
There are two retry mechanism to handle timeout error
But sometimes It just doesn't connect
In the logs Sang sent, The retry function tried to connect for more than 3 mins and It was still trying to connect ....
I confirm, No problem are detected on Flutter side.

After investigating more changing ISP solved the problem, The first ISP connection speed was 11 Mbps, Second one was is 22 Mbps.

According to our test, If the ineternet provider has higher speed than 11 Mbps, For example It is 22 (Which was the working ISP), The websocket works as expected.
Also VPN icreased websocket speed.

Just to finalize, If we get reports from India that connection is not stable, We will need to consider improving the service speed for India.
