SuperAdmin and inadvertently my IP address is banned - how to resolve?

SUMMARY: We use ExpressionEngine as the CMS for our nonprofit organization’s website. I’m designated as the Super Admin. When I was trying to delete a content item on our site this morning, for the first time I received an error message saying that I’m not authorized to do that. I tried several times to delete the content, then suddenly found myself unable to access the website at all (or the Control Panel) from my laptop.

• I tried to access from my iPhone, connected to my home ISP WiFi, and same problem: unable to access the website at all (or the Control Panel).

• I tried to access from my iPhone, connected to my mobile carrier connection, and success, I am amble to access both the website and the Control Panel.

MY CONCLUSION: apparently I inadvertently triggered an automatic ban on my home ISP IP address.

DESIRED OUTCOME: I need to remove the apparent IP address ban on my home ISP IP address.

STEPS I’VE TAKEN TO TRY TO RESOLVE:

• Using my iPhone and mobile carrier connection, I’m logged into my Control Panel, and I don’t see anywhere to remove the ban on on my home ISP IP address.

• The Blacklist/Whitelist module was not installed. So I installed it, and added my IP address to the Whitelist. That didn’t resolve the problem. I don’t see anywhere that I can remove the IP address from a blacklist.

• I’ve researched via Google and in this forum, and I don’t see any info on how to resolve the problem.

QUESTIONS FOR THIS FORUM:

• What steps do you suggest I take to remove the apparent IP address ban on my home ISP IP address?

• Or, will the apparent IP address ban resolve itself after a set length of time, and I can just wait for it to resolve?
