verizon.net email on Thuderbird not receiving email

[#1]

My verizon.net email stopped receiving email on 16 March 2020.  I am using Mozilla Thuderbird.  I have 3 verizon.net accounts and none of them are receiving email on my PC.  The accounts are being received on an iPad, iPhone 8 and Samsung Galaxy S7 though.  I also have a gmail account on Thunderbird and that is working fine.  I continue to get the error:  "incoming.yahoo.verizon.net: server error - please try later".  Can anyone help me with this issue?
