I also was once in your place and did not know where to turn and where to start. I was advised to get a Cisco certificate and then I would be able to get a good job. I found a company and recently passed the 2020 Cisco Certification. It was very simple, and most importantly cheap. Other exams are very expensive, and the company I found provides an opportunity to choose the right package. The exam itself went well, online. I was very helped by the company's employees working there. If you are a technician and you are looking for something like this, then I suggest you follow my example.
Try to connect to the Instagram account from another device. If you can do that, then it's a problem with the app you have on your phone, maybe you have to update it or to reinstall it. I have similar issues with Instagram a couple of times but it happened because of the password. So, my Facebook and Instagram accounts are linked and when I changed the password to my Facebook account, respectively the password for Instagram changed as well, but I didn't take it into account and I inserted the wrong password. I remember I was so scared that I couldn't log in to my Instagram account. Some time ago, I came across a site that provided promotion services https://igautolike.com/free-instagram-auto-likes, and they helped me to increase the number of followers, that's why I was afraid that I could lose my old account.
