wordpress login error

My password is correct. WordPress accepts it also, but after I login,there is an error saying the site can not be reached. If I go straight to my website, the top dashboard bar becomes white. I have no idea what happened and it has been like this for two days. My website is https://www.swjoyoflife.com. I tried different browsers but I had the same issue. Everything was fine until the day before yesterday. I think I upgraded two plugins on language woocommerce multilingual if that is the problem?

Please help, thank you in advance!
