If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

Microsoft wants to escalate the situation from Australia to the EU, what a surprise.
Hello all and welcome to another news article, this time we are focusing on Microsoft pushing the EU to accept law proposition from Australia.
For all of you who are not familiar with the given situation let me quickly explain. The feud began when the Australian government proposed a new law that targeted Facebook and Google specifically. The government said that it believed that both of the tech giants were using content from news outlets without paying.
Have you ever seen the little news snippets that Google or Facebook sometimes show its users to keep them up to date? These are lifted directly from news websites, and the Australian government claimed that this practice meant that people didn't bother visiting the news website. This then staved news websites of revenue.
As such, the government put forward a new law that would mean Google and Facebook would have to pay the source website for every time they displayed a news snippet. Facebook responded by removing its Australian news coverage in light of the law.
Google, however, put up a fight. It argued that its snippets encouraged people to click on it to read more, thus driving more traffic to the news website. It also said that such a law would be too expensive to maintain in the long run.
As such, Google threatened to remove itself from Australia if the law passed. This was likely a scare tactic, as 95 percent of Australian web users use Google; however, it actually opened the door for its rival, Microsoft.
Microsoft saw how it could push its own search engine BING to replace google. It of course went and reached the Australian government to assure them that BING is more than capable to fulfill its needs and fully abide by the proposed law.
Now Microsoft knows that if this law passes it could see a similar situation happening in Europe and it is pushing it. US News reported on how Microsoft plans to encourage EU countries to adopt this new law too. The company has teamed up with the European Publishers Council and News Media Europe to make the following statement:
Publishers might not have the economic strength to negotiate fair and balanced agreements with these gatekeeper tech companies, who might otherwise threaten to walk away from negotiations or exit markets entirely
