GPS Error, No GPS Lock

PX4 Autopilot
1

Hi, I downloaded PX4 to my drone using QGC and I got some error on GPS.

So, I can fly it but cannot use return mode due to error in GPS.

Als, No GPS Lock for Vehicle signals on and I cannot get any GPS…

How can I solve this problem? I attached MAVLINK Console Log about GPS,

Hi Choky,

Which Pixhawk and GPS are you using?
Can you share the flight log link?

@Choky
Are you sure the connections are all correct, and the environment you are in has GPS? (open environment without any metal structure over your head)

Which connections are you talking about Mr. Lim, I tried my gps outdoor but I got this error and my GPS is not blinking green also:
