When importing a solution to a production environment from a development environment I get the following error:
No response received: Network Error (ERR_NETWORK).

Both solutions are unmanaged.

Hi @KK-20011057-0

Firstly I must warn you against using unmanaged solutions in production.

As for the network error, can you please provide details about what is in the solution.

@Michael E. Gernaey there is a Power Apps app and Power Automate flows with connections to Snowflake, SQL Server, Sharepoint and OneDrive for Business.

Hi @KK-20011057-0

Was it an unmanaged solution every time you install it?

Did it require you to recreate the Connections?

Do you ever directly create things in productions, whether in solutions or not? Did you or anyone else ever change anything IN this solution, including one of the connections, before you are trying to install the one from Dev.

Again I just re-iterate using unmanaged in production is bad.

Hi @Michael E. Gernaey, thank you for your help!

1. Yes, it was unmanaged solution every time, it worked last 10-ish times.

2. No, I didn't need to recreate the connections.

3. No, I don't implement changes directly in production either within or out of the solution.

I tried to do it with the manged solution and the outcome is exactly the same as with unmanaged one.

@KK-20011057-0,

Please try importing again using classic instead of modern by navigating to (settings - customization - solutions - import)

But why in production environment importing as unmanaged solution?

It's a test environment with production configuration, I tried with managed solution but the issue is the same.

Help me resolve this issue didn't help, it was empty, logs were also empty.

The issue was the size of the solution package, I reduced the size of images and now it works, also for the unmanaged solution.
