Many SEOs are reporting error messages when attempting to submit URLs to Google Search Console for indexing.
When attempting to submit a URL using the fetch and submit tool, it shows “An error has occurred. Please try again later.”
This does not seem to be affecting all accounts, as some are reporting that some sites have the error while others do not. I do not see the issue (although it could have just been fixed).
There is a workaround for those having the error issue. If you crawl the page using the mobile friendly testing tool, there is a way to submit your page to the index which is working. This method does not require the CAPTCHA, which could possibly be the source of the problem.
Do note that you do not need to submit URLs to Google as the only way to get a page idexed. Adding a sitemap can also kick start indexing, and if it is a new page on an existing site, you can also add a link from the homepage so Google can discover it faster. And links from external sites can also be used by Google to discover new sites and URLs.
Google is aware of the issue, so it is being worked on.

Also note that you can submit individual URLs directly to Google (regardless of owning the website) by going here https://www.google.com/search?q=submit+site+to+google

While the errors were happening, that one was also giving errors as well.
