DROPBOX: (7) Failed to connect to api.dropboxapi.com port 443: Connection refused
I am trying to connect a wordpress back up plugin -- BackWPup to dropbox. I have several webhosts and it has not been a problem. However on a recent attempt to authorize the application it was rejec...

Dropbox StaffThe Dropbox API itself wouldn't refuse your connections like this; rejected calls would receive an explicit error, such as a 429 rate limiting response. Further, I just tried and the Dropbox API servers are currently responding successfully.
It's possible you're seeing a network-level issue though. Is there any software, e.g., proxy, anti-virus, firewall, etc. on your network connection that may be interfering with the network connections to Dropbox? If so, unfortunately, as that's out of our control, I'm afraid I can't offer insight on configuring those. You may need to contact your network administrator for help with that.
Hi Greg K. and thanks for responding.
I don't know what to do. I have 2 other web hosts where I don't have any issue whatsoever with the plugin and all works OK.
On the other hand this other webhost says the ports are open and that they are having an issue with drop box not receiving them as stated above and asking for any DB assistance that may help solve the issue.
As far as network administrator, I do not know who that is. There is the webhost company, the plugin creators and me, the website owner.
At my end I have tried everything wordpress usually recommends:
UPDATE & FYI - I have done the following before contacting you:
I have tried 4 browsers: Opera, Chrome, Firefox, Waterfox.
I have disabled all extensions on the browsers and cleared the browser cache
Logged in to the website: All plugins, themes and wordpress are up to date.
In WP I have disabled all the other plugins : (I removed the Wordfence firewall and cleared the cache)
In WP I have used the twenty seventeen theme.
I am still unable to authenticate the DropBox API getting the same message:
DROPBOX: (7) Failed to connect to api.dropboxapi.com port 443: Connection refused
All, I know is it worked fine until dropbox recently required me to re-authenticate the api because of something they changed at their end.
I cannot connect, I'm not a tech and being stuck in between 3 different parties trying to co-ordinate it.
Again, thanks for you help

Thanks for the additional information. From your description, it sounds like your web host would be your network administrator this case.
It does sound like there's an issue with that particular web host, since your other ones are working, or at least a networking issue on the path between that particular web host and the Dropbox servers.
If you'd like, I can ask our team to check if there's anything they can see that would be causing this (though I can't make any promises as to what they'd be able to find or fix from our side). In that case, open a ticket here and supply the output of the following from the affected host:
Mac/Linux:
traceroute api.dropboxapi.com
Windows:
tracert api.dropboxapi.com
Thank you. I will forward the tracert request to the webhost.
Update: I heard back from the backWPup plugin developer with this response:
hmm, so in this case, you have to contact Dropbox support and ask them why they blocked your IP.
Sorry but that all I can help you now
For now, I would suggest you use another backup destination like FTP, AWS S3 or Google Drive(pro version)- Greg-DB
Thanks! We'll follow up on your ticket.
