I started getting this error today and don't know what the cause is.
Hi,
Check if SDDC Manager is connected to the Internet.
If this is an offline environment, please follow "Offline bundle download fails to update LCM 2.0 manifest" here:
After re-reading you message, I think this can also be a browser cache issue. Try deleting your cache, log out/back in to SDDC Manager, and try again. Or try another browser.
SDDC manager is connected to the internet. I can see the new bundles available for download. They appeared yesterday. Also, I hoped briefly that it was a browser cache issue. But after deleting the cache and relaunching the browser there was no change. Unfortunately, in the environment, which is accessed currently through a jump host I don't have another browser that I can try. However, my instinct tells me this is not a web browser issue.
It turned out that there is a bug in vcf 4.2 that was causing logs not to rotate. I had a huge log file that filled up SDDC manager root. Once GSS figured this out and got rid of it everything went back to normal.
