Help S7 Edge Issue - Security Connection Error

[Jeff S Wright]

Having issues with my S7 Edge....I'm unable to update (sync) my email account. Have been receiving "security connection error". Deleted email account....tried to re-install but now receiving:

"Unable to set up account"
"A security connection error has occurred."

What's the issue and how to fix it?

Thanks!
