SNAP 8.0 version Apply orbit and connection problems

Hello guys,
I am using the SNAP version 8.0 and I am facing some issues with the gpt. The weird thing is that I started having these kind of problems some days after having using it, because at the beginning it used to work fine.

So the thing is that I would like to be able to process simultaneously many subswath, so I tried through 3 options (snap gui, graph builder tool or gpt through terminal) launching the same graph, but I always have problems of connection, it says many times “connection reset” until it get crashed. I checked my connection through Tools–>Options–>WWW and it works fine.
Thus, I tried to reduce to a very simple graph like “read”–>“applyorbit” (with or without the check to fail if it does not fine the orbit)–>“write” for a single image, and again it does not work.

The characteristics of the system in my machine are: Linux 5.4.0, Ubuntu 20.04, Java 1.8.0_22 with a VM of 64-Bit.
Here it follows a list of the errors I get:

  • through gpt on terminal:

I also checked and the firewall does not block the 443…

Finally, I also tried to uninstall the 8.0 version and using the 7.0, but I get the same errors.

Can someone help me with this problem?
Thanks a lot,
Diana.

Just guessing: could it be an very recent image where no precise orbit information is available yet?

Thank you for the reply :slight_smile: but I don’t think because it was from Nov 2019…

The internet has been having problems. I find it helps to avoid “peak” hours at both your site and the remote site’s location. When possible, I try to do downloads separately from processing so I can make sure the files are all present and correct, rather than having internet glitches loose a bunch of processing work.

You might be encountering a limit on simultaneous connections to Copernicus. This might occur if you started a number of orbit updates in parallel (simultaneously).
For production I replicate the orbit database locally so that I can avoid issues as @gnwiii noted. The files go into your home at the directory structure here: ~/.snap/auxdata/Orbits/Sentinel-1/
Also note that ASF.Alaska.edu has a repo where orbit data can be downloaded if Copernicus has an issue.
