Hi @luism,
I agree with @Africawaterdoc suggestions. We have some tips on what to try when you can’t get corrections from the NTRIP service in this post. Please go through them. I recommend removing the NTRIP credentials from the app and reentering them once again to eliminate the chance of typos.
Also, let’s double-check that your receiver has a stable connection to the internet. Have you tried connecting to other mount points? Was it of any help?
