Hello everyone!
I have a piece of code that used to run perfectly on blynk. I tried going back to it today to make some changes and suddenly it could not keep a stable connection to the server anymore. After some testing (mainly comparing it to the quickstart template which connected fine to the server and then porting it into the quickstart code little by little to see which piece of code made the connection to the server fail) i figured out that the issue is in the setup function. Namely, the pinMode declarations, as that is the only piece of code that, once ported into the quickstart template, causes the connection to become unstable. However, i have no idea why this even happens. Has anyone else experienced this and/or sees the issue with the code?
TIA!

Blynk.virtualWrite(V1, value);

Blynk.virtualWrite(V2, millis() / 1000);
}

Serial.begin(115200);
Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass);

This is what the serial monitor looks like when the above code is uploaded to the board. It just keeps going:
