Connection issues - WiFi or mobile (cellular) data

• Internal Server Errors (ISE) primarily arise from local connection issues.

• Using a stable 5G Wi-Fi connection inside my condo resulted in no ISE during the last PvP wave.

• However, on the balcony, the same connection occasionally caused ISE, and switching to mobile data improved stability.

• Mobile data inside concrete walls proved less reliable. So do concrete walls between your router and your device.

• For optimal signal reception, avoid obstructions between the router and the device.

• If connection problems persist, consider using a signal booster.

Some can increase your signal strength up to 32 times.
