🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 22

Now open your browser and type in your HTTPS/SSL certificate like this https://maybe.yourname.synology.me that you have previously created at STEP 6. In my case it’s https://maybe.mariushosting.synology.me Click Set up account. Follow the instructions in the image below.

• STEP 22

Type in your own details, then click Continue. Follow the instructions in the image below.

Enjoy Maybe!
