I’m aware that recently, seemingly all of WXSIMATE’s synoptic data sources (I don’t use SYNOP myself, preferring METAR) have quit working. The FSU links are affected by their decision to require (free) registration. I haven’t tried registering yet. Have any of you tried? And have the links changed?
The one I was working on tonight is the COD (digatmos) one. The URL is now https instead of just http, and I tried hard-coding that change, but it still gives me a “cannot establish connection with the secure server channel SSL/TLS”, or something like that. This isn’t a field of expertise for me. Doers anyone have any ideas or information?
Hi Tom.
The fix should be relatively simple.
WXSIMATE is requesting the data using TLSv1 but the website is wanting TLSv1.2.
Your assembler should have a process for the upgrade of the TLS procedure.
The actual error received by the app is Fatal alert, Handshake Failure on the TLSv1 protocol.
The process for redirecting to https is working ok. WXSIMATE is being redirected to https:\ but is then failing due to the less secure TLSv1 handshake.
Thanks, Rob! I tried it on a newer computer, with Net Framework 4.6.2 already installed, and it supports TLS 1.2, and worked fine. So, I think it’s just amatter of telling users to download and install the latest Net Framework upgrade. Easy enough!
I run wxsimate while sniffing the network with wireshark to see what packets are being sent and received.
using a brower on the address has always worked. m1 has 4.7 and m2 has 4.8 both give the same result from winsimate.
Really strange … I had tried the COD synoptic data last night, and it worked, but tonight, it’s not! When I try the address directly in the browser window, it works, even if I use http instead of https, so I think that part redirects. I’m researching possible solutions, and I’ll post here when I figure something out!
Update: might have a simple solution … a proxy server - same one Sam Bohler set up for the GFS and WXSIM-Lite data. This might be an easy way to head off similar problems in the future as more sites go secure. Hoping to have a fix soon!
