Can't send emails through Office 365 SMTP - Client host blocked using Spamhaus

Issue

Windows server and Kyocera photocopier can no longer send emails through Office 365 SMTP server (domain.mail.protection.outlook.com). The issue started happening after ISP change (new ISP was UK's PlusNet). After checking PowerShell mail send script output I found following error:

Google Home Bluetooth issues: "Sorry, power controls is not yet supported"

I play music on my Google Home Hub through an external Samsung Bluetooth speaker. The initial pairing has to be done from Google Home app, but after this, it's sufficient to say "Hei Google, connect to Bluetooth" and Google Home would say "OK, looking for paired devices" and almost immediately connect to the speaker. This worked absolutely fine for around 6 months and then suddenly Google Home Hub instead of connecting to Bluetooth would respond "Sorry, power controls is not yet supported..."
