Cannot reach email sign-in page.

Postby cegray720720 » Tue Mar 26, 2019 10:52 am

I am on holiday in Thailand and cannot reach the sign-in page for my email.

When I do a search about my email provider this is one of the returns...

Mediacom Webmail Log In
Zimbra provides open source server and client software for messaging and collaboration. To find out more visit

So here I am asking for help.

My ISP is Mediacom ( I can access the Mediacom homepage, but cannot access support, my account or the email sign-in pages.
(I used my back up gmail account to register for the Zimbra forum, but people -- and airlines, etc. will use the mediacom account to contact me.)
I have used Mediacom email on multiple trips, including Japan, The Dominican Republic, Canada, Mexico, and throughout the United States. Yes, I was able to use it last time I was in Thailand two years ago -- but this time no luck in Thailand or Indonesia.

In EDGE the error is the standard "Can't reach this page" message...
Hmmm...Can't reach this page
Try this
- Make sure you’ve got the right web address:
- Search for ""
- Refresh the page

In CHROME the error is the Sad Face Page...
This site can’t be reached took too long to respond.
- Checking the connection
- Checking the proxy and the firewall
- Running Windows Network Diagnostics

Note: I cannot reach the sign in page -- I do not even get a chance to input my Username/password.

It would seem to me I should be contacting my ISP (Mediacom) but as mentioned above I cannot reach any of their login pages.
Any suggestions?
Can the Zimbra support team give me any assistance, even if it is only to serve as an intermediary with my ISP?

Thank you.
