Topic: Roundcube works fine but blocked in thunderbird
Hi, my problem is blocking auth in thunderbird (or other mail client).
I have one public ip, few physical servers and lot of hyper-v virtualized machines. Im using nginx proxy manager for reverse proxy. iRedMail is already installed on new physical machine. Everything is working properly in roundcube, but when i try to connect with thunderbird im getting error. If i leave this for an hour, first login and the first email will be sent correctly, but subsequent emails will be blocked. Here is log:
