ByteSpace still had old energy-related queries in GSC, which do not match the current hosting layer. Google likely remembers previous content or links.
The essentials are a clean sitemap, matching canonical tags, no old 200 pages, topical internal links and measurement after a full crawl.
Random content will not fix it. Clear pages about hosting, mail, backups and Hostilla migration are the better path.
For everyday hosting, start with Hostilla. For dedicated infrastructure, servers or colocation, continue with DataHouse.
