If you're using freenode.net for IRC, I suggest registering the same nickname on libera.chat
Typically as follows:
* connect to irc.libera.chat port 6697 (TLS)
* set your nickname: /nick hodl
* register it: /msg NickServ register PASSWORD firstname.lastname@example.org
* do what the confirmation email says
