I am unable to download and upload files with my dropbox now. I am 100% sure that my internet connection is not the issue as my recent speed test, 4k test, Netflix test, Youtube test google drive test are all working fine. I tried pinging the site directly from cmd and the connection is intermittent. Other sites are working perfectly. I hope someone can check if this is a server issue or an account issue. I contacted support and they are also clueless about what is happening.
