UEMS/WRF EMS Unofficial Forums

As far as I remember, gfsp25 and gfsp25pt and other gfs datasets switched over to FV3 on the 12 June this year.

The other 3 clusters, running 18.1.3 all requested ptiles at the same t...

It does not work in version 18.3.1

My setting is DSET = gfsp25pt,previous

When gfsp25pt finishes its tries and sleeps, I get an error message.

I have been having problems getting initialization data from the gfsp25pt server.
Has anyone else noticed this in the last few days?

I also suspect that it is related to 18.3.1 update since it started after I updated. (May just be a bit of paranoia )

It looks like a network issue.
I tried the new install program a few hours ago and It was connecting OK to the servers.
