@shutton - I have not heard of anyone running into the issue you are experiencing. Which particular models have you run into this error with? Are you able to restart the upload and have it complete or does it consistently fail? It would also be good to see one of the config files you had issues uploading. I will provide you with a method to provide the config file privately.
If you run into this issue, there are several ways to upload the configuration using the CLI as well. These method are outlined in the document below. Although the guide refers to a factory-default config, the process will work with any configuration you wish to upload.
Let us know if you have any questions.
By the way I think we have narrowed it down a little. It will upload fine when we are onsite. The issue seams to be remotely over https: that we have the issue. Let me know your thoughts.
Looks to be limited to https specifically, rather than which interface or security zone you use to communicate with the unit. We typically don't use https when local, but I just tried it here in our office and the same behavior results. Tested using Chrome and IE9; no difference.
I apologize for the trouble you are experiencing. This appears to be related to browser settings for IE9 or Chrome, when using HTTPS to upload a configuration from on a remote subnet. We will continue to work on this issue and let you know when we have an update. In the meantime, you can workaround this by doing any of the following:
- Use the CLI, as suggested by Noor previously
- Use HTTP
- Access the GUI from a local subnet
- Use the web browser Mozilla Firefox
Please, let me know if you have any further questions.
