Social-media star Nash Grier has been frozen out of his YouTube account – and the Google-owned video service says it’s working to help him restore access.

Grier has 4.8 million subscribers for his YouTube channel, which is affiliated with AwesomenessTV. He’s had the YouTube account since 2012, but only started posting new material on Aug. 31 with a “Hello” video, in which he captioned, “Can’t wait to show you guys what I have in store for this channel!” Grier also has 10 million Instagram follower and 6.8 million on Twitter.

According to a source familiar with the situation, the problem was basic human error: Grier accidentally disabled access to his YouTube account.

On Sunday, Grier tweeted, “Got locked out of my YT account 😩 I’ll have videos up as soon as I’m back in.” He followed up two hours later asking followers, “Should I just post the videos directly to twitter or wait for youtube support? 😂”

YouTube replied to Grier Monday afternoon on Twitter, saying, “Our Creator Support team is reaching out for further help, hope this gets resolved soon!”

According to Melinda Morris Zanoni, CEO of Legacy Talent and Entertainment LLC, which reps Grier, his account encountered “technical difficulties while trying to upload a video.” She added, “we are on it and he’ll be up and running shortly!”

Grier, 19, rose to fame on Vine, the now-defunct 6-second video platform that was part of Twitter. He’s appeared in Fullscreen teen drama movie “The Outfield” — which topped Apple’s iTunes drama movies chart in November 2015 — and Fullscreen’s “The Deleted” series, as well as Netflix’s “You Get Me” from Awesomeness Films.

His younger brother is Hayes Grier, who’s also a social-media star and is featured in reality show “Top Grier” on Verizon’s Go90.
