The api freezes if an error occurred while connecting

[frameorigin]

Issue
Sometimes it is not immediately possible to connect to some nodes. For example, the Basilisk node sometimes interrupts the connection attempt. In this case, the program freezes during its execution on 'await', without throwing an error through 'throws'

Steps to reproduce the issue

1. Open the project
2. Run the project several times before reproducing the connection error (accompanied by a characteristic log) [Alternative option: run without internet access]

Expected result
The program comes to print("Success") or print("Error: \(error)").

Actual result
The program does not reach the above lines and freezes
